u/Farisaico

Inspired by this graph from a deleted Arknights post.

Calcs made based on this S-Rank Pull Distributions post. 500,000 simulated pull sessions for each category, assuming that:

• Character: Flat 0.6% pulls 1-74, then grades linearly to 100% pull 90.
• W-Engine: Flat 1% pulls 1-64, then grades linearly to 100% pull 80.
• Average cost: Buying only 6,480 Monochrome packs for 99.99€ each, without any first-time double bonus.

Graphs made with Matplotlib (Python).

I probably won't make any other graphs, I was just curious.
