in theory, using 20% chances 5x makes the odds only around:

first try 20%

2nd try 36%

3rd 48.8%

4th 59.04%

5th 67.232%

100% odds are a guarantee. but if you use 20% odds multiple times, theres always a chance for each try to fail. but, theres also a chance that you wont use as many cards in the attempts. i personally aim for around 80%. 4:1 odds of success, but not wasting excess cards.
