Hey Mich, I came up with this idea of making a calculator that will approximate one's chances of winning the unit they want with "n" amount of summons. It includes rate up modifiers and a list of units for ease of change with every different gate. It revolves around the formula:

1-(x)^n      x: 1-(variation of unit / pool of units * rate up modifier)      n: amount of summons capable

I.E: Let's say I want to summon Elza 4* or 5*  from the rare summon gate. The rare summon gate contains approx 304 units in it but has no rate up, making the modifier x1. I also can only summon 5 times. Therefore, I have a 2/304 chance with 5 tries. The calculator will read:

1-(1 - (2 / 304 * 1))^5

= 3.25% chance of getting Elza

What I want to do with this calculator is provide players a nifty way to see their chances of getting the unit they want before they put all of their eggs in one basket. I have a google spreadsheet all pre-planned with the list of units in each arc and formulas implemented in it. Please reply if you're interested and/or can help me out. Cheers mate!
