Count them? Ahem well err... Yeah in the beginning I kept both a log and a diary. By date recorded products, shave results, any bugs and took photographs. Designed experiments to fix bugs and rechecked results.
Took USB microscope pictures of my skin and the blade. Read endlessly on SRP. Around 50 shaves it clicked, I kept all the data logging going for another 50 or 60 shaves.
Now I just shave and rotate the products, all my shaves vary between good, great, and perfect. Since I don't really have any serious bugs now (burn, stubble, bumps, cuts, and so forth), I don't feel the need to log everything.
So no I don't count anymore, but I sure did in the beginning. I recorded everything like a lab experiment.
It helped me turn the corner at 50 shaves. YMMV
Best,
Ed
