The relationships are:
25/255 = 11.11%
40/225 = 17.77%
Increase = 17.77 - 11.11 = 6.66%
Same as 15/255 = 6.66%

Hi Yvon,

My interpretation would be the 25 to 40 ml increase represents 15 ml of
alcohol.  That would represent
15 ml alcohol / 200 ml fuel + alcohol = 7.5 %

I've never actually done one of these tests, so if I've got it wrong
let me know. :)

Bob W.
