I feel like 100/day is swinging the pendulum in the opposite direction. I apply like 3-5/week and I feel like that's a lot.

Granted I don't live in a tech hub so my options are limited but 100/day feels like you're just spamming aimlessly and wasting your energy on quantity instead of quality.

At 100 resumes/day it's hard to believe that you're optimizing them for the position or for that matter, doing anything other than shotgunning.

You're far more likely to get 100 rejections doing this than if you research a handful of the positions and send targeted resumes to those.

OP said spree, not 3
