Gradual Selection: Image count selects almost all points

[holgar]

Hi,
I have a questions about the Image Count filter in gradual selection. I make photos of objects at the size of a bottle. I use many images....100-200 21 MP images with a fullframe camera.
I get fairly high number of matching points (around 300.000). Anytime I try to use the Image Count filter of 2 almost all Points get selected. Like 250.000 of 300.000. Is that normal? I guess its not good to filter that many points for optimization.
What am I doing wrong? Do I need even more overlap? I do Turntable Fotos which I mask. and I take about 36 Images per round.

Any Help would be very welcome.
greetings, Holger
