- It compares average outcomes with 50% and 90% success thresholds and models synthesis using user-entered material counts and success rates.
Field notes
The gacha workflow accepts game rates, target counts, pull size, and either currency or cash costs, with an optional budget input. Synthesis can be added by specifying the required lower-tier cards and success rate. Other sections model upgrade failure consequences and compare repeated hunting measurements; the page says those records are combined using a time-weighted average.
