I'm new to LeetCode, and I was curious if anyone noticed your speed percentiles varying between two identical submissions? I was messing around with algorithm optimization for an easy Pascal's Triangle question and I went from 70% speed to 6% between submission versions after some changes. This surprised me given that it should have made the code faster, so I submitted the identical code a second time and it went to 75%. I was wondering if anyone has noticed this apparent discrepancy? I'm not mad about it or anything, just confused.
