Rings run from 3 pm at the centre to 11 pm at the edge. Schematic: A shape of the facts, not a picture of a particular date or a measured outline. Each month is its 30th, or the last day of a shorter month, not a promise about the other days.

The dining table is open for dinner outside 8:00 PM to 9:00 PM, August to September. It opens at different hours October. Shut November to July.

  • November to July: shut for dinner outside. What it feels like stops it in 5 of those months and privacy exposure in most of the rest.
  • August to September: open 8:00 PM to 9:00 PM.
  • October: open 6:00 PM to 7:00 PM. What it feels like is what closes it.

The shut months are not shut for the same reason. What it feels like closes 5 of them and privacy exposure closes most of the rest, so a single change will not open the year — it will open part of it.

The dining table for Dinner outside. October 30, 2026 at 2:01 AM, America/Denver. Now on this date. Confidence low. Cause: What it feels like is what stops it.

Sit down, eat, and still want to be there ninety minutes later.

Dinner outside

The dining table does not work for dinner outside right now, and what it feels like is why.

“No” means the model does not support this use under the conditions being read. The controlling limits are listed below.

Your 2 rechecks at this spot read it 12 lower than the model’s 44 on the 0–100 reporting scale, which is mapped from the physical readings and is not itself a measurement.

  • Past the limit What it feels like is about 35°F — 24°F under (at least 59°F)Estimate: Worked out, but at least one input was assumed rather than measured.

    The air is 41.9°F. It feels about 6.9 degrees cooler than the air, near 35°F.

    Nobody finishes a meal in a seat that is cooking.

Still unanswered:Noise
Why it is unanswered
  • Noise. Nobody has told us what the noise is like here, and it is not something geometry can infer.

What would change this. This would change if what it feels like were measured rather than estimated, or if noise were measured.

Confidence low (50%). Treat this as a starting hypothesis, not an answer.

What next here

Proving it well enough to spend money

7 of 8 milestones. The forecasts have been checked against what actually happened, so a figure from here can go to somebody who will charge for it.

  1. Getting an honest answer4 of 4 done
    • Placed on the earth — done. The sun is in the right part of the sky for this address.
    • A spot to read — done. 2 spots are being read.
    • What stands in the way — done. 4 things are drawn, so the shade is worked out rather than assumed.
    • Who can see in — done. Privacy and sightlines can be answered here.
  2. Testing a change2 of 2 done
    • A change tested — done. 3 changes have been put on the record.
    • A forecast checked — done. Across 2 rechecks the forecasts have been out by about 13 points on average. That is a lot, and it is why this is recorded rather than assumed.
  3. Proving it well enough to spend moneyyou are here1 of 2 done
    • Corrected against reality — done. Readings here are adjusted by what was actually observed.
    • Photographed — not done. A photograph is what turns a drawing somebody sketched into a drawing somebody can check.
  1. Go and see whether "Move the table 8.2 ft north, under the house shadow line" worked

    The forecast for this has come due. Checking it is what turns this from a model's opinion into a measurement of your garden — and it is how the readings here get corrected.

    stand there at the hour it was forecast for
  2. Read all 2 spots at the same hour

    Moving where you sit is free, immediate and reversible, and it beats most of what you could build. Read side by side it is usually obvious which corner was always going to work.

    a read, nothing to enter
  3. Get this place to Annotated

    A photographic check on the mapped sightlines and geometry. That makes privacy estimates more credible, but does not replace measured dimensions. Right now: Sightlines drawn from mapped observers remain provisional until their positions and heights are checked. The drawn heights have not been verified against the actual place. What is missing: Photographs of the actual place: None annotated. A photograph is how a drawn height gets checked against a real one. Photographs that know where they were taken from: No photograph has a position and a bearing, so what is marked on them cannot become a measurement.

    2 things left
3 more things worth doing here
  1. See how this spot changes through the year

    A terrace that works in July can be unusable in September for reasons that have nothing to do with temperature. The same geometry read in four seasons is the cheapest insight here.

    a read, nothing to enter
  2. Photograph the spot and mark what is in shot

    A photograph is what separates a drawing you sketched from a drawing somebody else can check. It is also how heights get corrected without a ladder.

    one photograph
  3. Turn this into something you can hand to somebody

    The forecasts here have been checked at least once, which is the point at which the figures are worth putting in front of a builder rather than a friend.

Mapped
  1. Quick
  2. Mapped

  4. Measured

Shade, sky view and daily light are computed from the geometry on this plan. Unmeasured dimensions remain estimates, not verified measurements.

Sightlines drawn from mapped observers remain provisional until their positions and heights are checked. The drawn heights have not been verified against the actual place.

To reach Annotated

  • Photographs of the actual place: None annotated. A photograph is how a drawn height gets checked against a real one.
  • Photographs that know where they were taken from: No photograph has a position and a bearing, so what is marked on them cannot become a measurement.

What that buys: A photographic check on the mapped sightlines and geometry. That makes privacy estimates more credible, but does not replace measured dimensions.

Everything that was checked
  • Quick A place on the earth: Denver (demonstration), with a time zone, which is what makes an hour an hour.
  • Quick Somewhere to read: 2 spots marked. A reading is a height at a place, and moving it moves the answer.
  • Mapped The things in the way: 4 objects drawn. The house counts, and so does the neighbour's.
  • Mapped What is underfoot: 2 of 2 readings sit on a mapped surface.
  • Mapped Where the property ends: Drawn, so the product can tell you when the cheapest fix stands on someone else's land.
  • Annotated Photographs of the actual place: None annotated. A photograph is how a drawn height gets checked against a real one.
  • Annotated Photographs that know where they were taken from: No photograph has a position and a bearing, so what is marked on them cannot become a measurement.
  • Annotated Who can see in: 1 observer marked.
  • Measured Heights off a tape: 1 of 4 objects are measured. The remaining 3 are this product's own inference, so no figure here is a survey figure yet.
  • Measured Something checked against the day: Nothing has been checked against a real afternoon. The model is unopposed, which is not the same as being right.

What to measure next

None of the measurements tested here changes the recommendation enough to rank next. This checks only the listed assumptions and ranges; other inputs can still be uncertain.

Reading at

2:01 AM·October

The sun is down.

October 30 · The dining table Schematic: A shape of the facts, not a picture of a particular date or a measured outline.
  • Tight (lined)
  • No (pale, edged)

The sun reaches the dining table at 7:27 AM. The dining table loses the sun at 2:17 PM because of the maple. The dining table comes back into the sun at 4:02 PM, once the maple is no longer in the way. The dining table loses the sun at 5:31 PM because of the West fence.

The evidence behind this whole day is thin, so nothing on the strip is marked out as worse than the rest. The shape of the day is still the model’s best reading; the confidence in it is low, and it stays low until something it needs is measured.

The dining table is open for dinner outside 6:00 PM to 7:00 PM.

About 1 hours in October, and what it feels like is what closes it.
