I re-measuered on a steel table and twice I got the ratio above 5.6. Means little as it is not properly fixtured to get an accurate measurement. I trust Bobs process is centered around his model with reasonable distribution.
A little disappointing as I was hoping to gain more leverage, but hats off to Bob for building it right to begin with and I do remember the pedal being firm. The only time I stood on the brakes was in the rain going uphill on a 180d switch back and it spun the car immediately and I was not nearly quick enough to catch it (UPHILL). I blew up the motor shortly after so that squelched my learning.
if you guy's could help me with the simple stufF - my Metrology skills have always been lacking - I do not have the patients over long periods of time (anything greater than about a minute anymore- I was better when I was younger).
