There was a rough estimate 200,000 AV albums in Japan that literally can't sell any copy. so AV actresses are not scarce resource. Many AV productions are at very low cost. I often think i can do a better AV with my existing equipment. Only a few famous AV produce companies do quality movies.

Many WLs in Japan would do a few AVs in order the claim upgrade their rates to AV star make more money. This will explain why these AV actresses at the shops only have very few AV videos.

My experience is that AV girls don't make any difference. I don't avoid them particularly but I am not apppearled either. However the extra 10-15% charge does put me off sometimes.
