Last year I threw together a Windows program to computer frame angles from length measurements. Indeed just playing around with small changes in length produces enough angle variation to show the sensitivity. You can download it here:

It's a fun toy (and accurate) but ultimately not very useful for that purpose.
I'd be more interested in your correlation between perceived handling and those measurements. I'd bet it isn't so cut and dry as it might first appear. If it is, then great.
