I sort of get it now. Correct me if I'm wrong:


 * 1) The game assigns an arbitrary value to each thing that can have random chance (blessed evo, upgrading etc.). This number is not a percentage, but we can call it a rate X.
 * 2) Whenever it's time to decide whether the player gets something or not, we generate a random number between 0 and 1 (or 0 to 100% if you'd like). Call this number Y.
 * 3) If X > Y, we have success, otherwise failure.
 * 4) Thus, If X > 1 (or 100%), you will always get success.

This doesn't explain the numbers in the first post, but it's what I understood so far.
