Or maybe you get a tailwind more often on one than on the other, or you have a bigger breakfast when you ride one of them. Maybe even a bit of everything.
First of all, two brand new identical bikes are not going to be exactly the same. Second, you need to see that 354 rides nullifies "breakfast" and "winds".
I realize I didn't put this in an earlier, I've been riding this segment for 4 years. This nullifies issues of tires, drive train, ... Many components have been changed out on these bike. The only bikes that doesn't apply to are the Pugsley and Mondonico since they are both new to me in 2015.
Yes, fit is a subject of interest. The Mondonico is more aggressive than the Felt and this has taken some time to get accustom to. This goes back to an earlier post about the Mondonico being new and need more time to get comfortable with it.
There are also issues around a 20 year old derailleur and shifters, and 20 year old wheels on the Mondonico. The wheel set is the most likely thing to upgrade because I love the first generation Campy Ergo shifters.
