OK two weeks after hatch, Things 1-4 weigh: 5.6, 5.7, 11.4, 6.1 oz So Thing Four, in spite of his lesser birth weight, is putting on weight faster (and visually appears more compact) than Things One and Two, but has no visible patterning at present, being basically black and grey (blue), with dark shanks. Thing Three, heaviest at birth, and mostly buff with a few splotches, has put on weights at something much closer to CornishX speeds than the typical. If I get similar breeding out of the next few incubations, and any useful patterning at all, these will be my preferred F1 pairings.
@RoostersAreAwesome I'm not here to argue with you. I have some sense of the POC. I am, however, telling you that these birds came from TSC, which in my region means Hoover Hatchery. All five of my birds are essentially identical, but for variations in the amount of melanin - one is darker, one is lighter, and three are photocopies. All are 19 weeks, about 4.3#, and as of a few seconds ago, look like this:

Just as they show on their website (look at the female in the foreground) - though mine are even less pronounced:

as I said, "Hatchery Quality". There is no rose to that comb, sadly. Again, 19 weeks, and laying. I don't expect that they will suddenly poof out a comb not yet evident. What they do have is, in many cases, similar to the bumps on my Brahma's beaks.
If my Hoover's so called SLW are somehow rrPp (likely) or rrPP instead of RRpp or Rrpp (as expected). I am in no way surprised. Add another generation or two of random crosses, and Hoover's flock pf "SLW" suddenly look like this:
