 * ... so I don't think I would risk ALL of my gems at once for the chance of only getting one SR

This is where you get it wrong. That one SR (or above rarity) card is a bonus. The bonus doesn't (or shouldn't) have any effects to the other 10 draws. The chance of obtaining certain cards in 5-gem draws and 50-gem draws should be the same for each draw.

Think of it like doing 10 single draws in a row, put the results on one screen, and add one bonus SR (or above rarity). Then ta-da, you get 11 cards instead of 10.
