The point is fit is pretty nuanced and often contested here. It turns out to be a bit of personal decision honed from trying many different fits to determine what works best.
As to pronouncing Roubaix...its pronounced RO-bay....O is long...accent on first syllable.
I'm actually a statistician so my mathiness will be a little different than yours. Making that matrix is second nature to me.
I think what is important in the next few days is to try the Roubaix style geometry and then perhaps the Tarmac and see which one, in both sizes, I like best.
I have a feeling I won't be able to tell from riding for a few minutes. Things like cricks in the neck or fatiguing arches, CHAFING, etc, don't come up until the ride is more than an hour.
Oh, god, chafing. I, of the thunderthighs, will be on the lookout for potential chafing.
Where does one usually chafe on a road bike? On my mtb if I chafe it's inner thighs about 3-4 inches down from the lady parts. IF I go for a long ride I'll wear compression shorts under my running shorts. I have yet to buy cycling shorts. I'm too pudgy for tights, get self-conscious (I'm very fit, just not very lean). I'll probably get the looser kind.
