One wrinkle in this is that the calculator assumes that all characters in the same rarity+category tier (i.e., SSR eidolons) have the same base draw rate. With the +100% eidolons, this assumption probably does not hold true; the draw rate for these (assuming you've landed an SSR eidolon) is probably much lower than 1/(total number of SSR eidolons). The draw rate penalty may be as large as an additional 1/5 or 1/10. I currently have no reliable data to estimate the exact penalty, however.
In short, don't include +100% eidolons as a 'hit' or 'miss' if you want a valid result from the calculator. They can only be validly compared amongst themselves right now.
