I've found you can predict the reward you're going to get for a reward.

The formula is X + (n-5)/5 * Y

X is a number between 0 and 100 and is equal to the table entry of your first reward. For instance, a Tower 2 Exterminate means your X is between 52.2 and 67.4.

n is the wave number, (n-5)/5 basically means "reward # after the first". 10 (your 2nd reward) -> 1, 15 -> 2, 20 -> 3 etc.

Y is the number added to X each time you get a reward.

So, if you get "Tower 2 Exterminate, Tower 2 raid, Uncommon 5 fusion core" as your rewards for 5, 10 and 15, your X was between 52.2 and 67, and your Y was somewhere around 15.

Landing on a 2% really helps solidify the numbers.
