dabrock, I know where you're coming from, I have almost 400 Astras plus about 70 Lab Blues and 50 GSBs, so there is really no reason to push each blade to 20 shaves for economical reasons.
However, I'm finding that I'm getting much smoother shaves from Day 3 - Day 7. Day 2 is smoother than Day 1. Close shaves are about the same from Day 1- 7. What this means is that as long as I'm getting the same 3-pass BBS shaves, it benefits me to push the blade longer and enjoy smoother shaves. Day 1 is like I'm using my face to strop the blade, Day 2 is much better but Day 3 and forward are the sweet spot for me.
I'm going to try for 15 shaves this time around, but I'll toss the blade the moment its cutting / closeness performance drops. If I can get 15 BBS shaves from one blade, that means I can change blades on the 1st and 15th of the month and eliminate 2 blade changes from my current weekly blade replacement schedule, which also means eliminating 2 1st and 2nd day not-as-smooth shaves per month.
