The way the site does the percentage, like most things on this site, is based on Wilson scoring, which uses fake data points to bias scores towards the center. The site is currently configured to add +2 positive and +2 negative, so given P positive and N negative, your ratio is (P + 2) / (P + N + 4). Given this, we need to determine how many flags 95% is. In an ideal scenario, we have zero actual unhelpful flags, meaning we just have the two fake ones. We can work out the math to find that you need 38 helpful / 40 total flags, or 36 real helpful flags. Since you have 30 already, you are 30/36 or about 83% of the way there, which is what is displayed[^1]. [^1]: This is technically a simplification because this is the ideal case with no unhelpful flags, but it's accurate for this case. When not in the ideal case, intuition somewhat starts breaking down for the formula used.
