Dang, all three look pretty darn good. You chasing numbers for a hotter core or what is your ultimate outcome? Put a count on there in the 10” so we have a better idea at just what size those patterns are. I had my best hot core pattern with a Jebs .570 in my Affinity but I also shot the .565 and .575. Either of the latter were 280 + or - with the Federal TSS #9 and a Sumtoy .562 was just a little hotter at 300 or so, all with a 26” barrel. I just got a 24” barrel for it so I am going to shoot a .565 and .575 Jebs again and a .562 and .570 Sumtoy. But by just looking at your patterns, the density looks good. Just need to be centered.
