GMR Fut pivots etc as far as I can see are:
1100 july 1, 2 bar SL for short 81.65
1200 july 1, Long above 82.25 (as MB asked, 0.60 as play room)
1300 july 1, made PH (discovered after 1500 bar)
1500 july 1, made PL 78.25 (discovered today after 1100 bar)
1200 july 2, made lower PL 77.80 (discovered today after 1400 bar) which violated prev PL by 0.45. If really 0.60 is play room for GMR then 78.25-0.60=77.65 was SL for long. 77.65 wasn't broken.
Then GMR took off to 89 or so.

Saint , how really to find the play room which in this case seems to be about 0.75%
