It’s been 5 years and that light is still poorly timed.
Might be helpful if you get a picture ticket, those lights need to be timed correctly, or at least they should post how many seconds the yellow is before the intersection. Give the drivers a fair warning that they want their money at any cost.
I replied to your first post before seeing this one. That is a simplified formula, but it is correct. If it did not meet that, you should have complained. Congratulations on getting it correct even if most on this webpage don’t.
