I had always agreed with Mike M on this. That is why the Japanese separate the males and females when they put them out to the mud in the summer. Something to do with the male hormones screwing up the growth rate of the females
However, I too have a mixed pond and I have 2 females, one is a Maruyama kohaku and the other is a Momotaro sanke. Both were jumbo tosai when I purchased them at the end of last October. The kohaku was 12.5" and the sanke was 13". They are now 19" and 21" respectively. I think it really boils down to the genetics the fish picked up from the parents and your water parameters and fish load. I currently have 33 fish from 12 to 28" in a 10,000 gal. system.
