botchee, be there a correct answer or not to your fine question, the difference is not a lot to talk about.

Pulling the 100% back to 78.5c lowers the fibs as such

100% 4c lower at 78.5
78.6% 3c lower at 67c
61.8% 2c lower at 58c
50% 1c lower at 52c

Given todays resistance is hitting the wall just under 60c, it seems fitting to use the high of 82.5c for the 100%

A quick google would suggest simply using the high and low points...
