At Open Days, people usually ask me how often the space is open.
I give them an unsatisfactorily vague answer (honestly, I don’t know).
Can someone pull timestamped, anonymised door access logs for arch 1 and 2 going back 6 to 12 months and provide it to me?
I’ll then vibe code a data-driven answer and share it with everyone.
Actually, shutter open/close data would be simpler and better!
Hey Brendon,
Yes, the shutter data is easy to get. I’ll DM you in a moment with it.
I usually tell people that if you’re an evening person then you’ll think the space is open 24/7; but if you’re a morning person then you’ll want to check the calendar.
I did something similar with the automatic lighting we used to have in Arch 2 -

The summary was:
However there are exceptions, if you want certainty then 12:00-23:00, at about 95% chance (in that data set) of turning up during any day and being open.

The issue is that these numbers are so average you get only about 40% chance of coming in and finding the space open during these dates according to AI.
If you let AI do the maths and hope it’s right, then you can hit 85% in the last 12 months using these times:
| Window | Span | Actual coverage | |
|---|---|---|---|
| Weekday | 11:15 – 23:15 | 12.0h | 85.1% |
| Weekend | 10:15 – 21:45 | 11.5h | 85.9% |
