I've just played a nine hole event at St A and found that the state of green was displayed as being fast. The first 8 holes were of a similar speed, the 9th very quick.
e.g., 9ft, I metered 9 and it came up 1.5ft short, as did the following holes given that I had allowed for up and down and sideways putts.
yes I did try to meter longer, but thats not the problem....fast should be fast, slow is slow etc. Given true that every course is different in terrain on the greens, is the green grown with different grass !!!
The real game can be seen to have true pace on the day whether fast , even or slow.
Maybe as a prelude to a game , there should be a practice green so one can gage the speed on the day
