OK, I'm still not satisfied and I don't consider the matter "laid to rest" but you have worn me down for the moment
One thing we agree on, these little beauties are certainly twichy and difficult to measure. On the other hand, I consider a 6% improvement to be a MAJOR improvement and am happy you pointed the way to it! I am also extremely happy as a 2 1/2 year owner to have one of the rare toys.
On a very positive note, you have rekindled my modding interest, so I'll probably go on to other mods. Thanks
