I was waiting for a P4 at the foot of HOR one Saturday lunchtime just after the last time this thread was current. I was there for nearly half an hour, and I made a note in my phone of how many vehicles were getting through the lights each time.

4, 3 (someone was sat on his handbrake), 6, 4, 5, 5, 7, 4, 7, 5 (the last of which being my bus).

There was a bit of amber gambling going on. I'd say 75% of cars turned right out of HOR towards Lordship Lane, though the slower speed of vehicles turning left meant that most of the threes and fours were occasions when there was more than one left turner.
