What are YOUR traffic pattern speeds?

We now have two 'thrashers on Potomac, as part of my airfield beautification program.

Curious what others use for pattern speeds. Short field?

Mine is full Robertson STOL

Approaching
I will get to pattern altitude 5 miles away or so.
I power back 3-5 miles away to slow to 140mph (120k) or so clean,
then drop 1/3rd flaps

Yes, yes I know flap speed is 160, but first I slow a bit and get some more headroom

Downwind
Then down to 110 MPH (95k) or so entering pattern and downwind

Abeam the numbers
Drop gear - starts descent, slowing

Base
Entering base 2/3rd flaps,
slowing down around 90 mph (76k)

Final
Turn final, full flaps.
Decelerate from 90mph (76k) to 80 mph (70k)
A touch of power on front engine
touching down 70 ish mph (60k)

Your turn. Just curious.
