thanx for the kind words - glad you're enjoying the experience.
OK the 3/16" .................
To begin, due to the angle of the installation a 25mm shorter shocker does NOT lower the seat height by 25mm [ Pythagoras and all that jazz ].
We arrived at the 3/16" after a full morning testing on a closed race track - with a qualified Club Racer aboard.
First we took measurements from 10 misc. Kays - 100's and 1100's. No two within the same group had the same base datum ! Sooooo - we took an average of all the data we had and started from there. Remember ALL sorts of influences can determine what geometery you actually have - worn springs [ front or back , tyre size, luggage / payload.
We set up the test bike with newish front and rear springs shox and started from there. We then tested the stock length [ 350mm ] shocker against the RAM, and then with the 325mm RAM installed - we did the same tests again.
The results are posted elsewhere but there was a significant drop in lap times on each occassion with the RAM.
We then left the Track Warrior to set up the bike as he wished - that's where we came up with the 3/16". HOWEVER, as long as you end up with 63 degrees - that's the OEM setting in a perfect World. depending on ALL the variables above, that's what you need to aim for.
I have a special frame that has been modified to give me a much steeper headstock angle and I'll try that out next year - it's NOT going to benefit Touring types, just something I want to try - along with the Eaton Mini Blower !
