Seed Count from Applejack Hips

Just curious about Applejack hips.

I just harvested Applejack x Suzzane and Applejack x Golden Glow.

Applejack x Suzanne had 2 seeds and Applejack x Golden Glow only had 1 seed.

Is this typical for Applejack? Perhaps this is a result of me emasculating early to help prevent selfing?

I had really poor percentage of hip set on my intentional crosses on Applejack this year. Quite a few op hips though. Perhaps I need to re-apply pollen more often.

Applejack so far has not set hips for me, except 2 this autumn. And they only contained 1 or 2 seeds. I find ir very hard to use as a motherplant.
