My thought is to number a d20 in increments of five, so 5, 10, 15, 20 and so on to 100. Most of the time that is all the precision you will need. If needed you could always throw a second die to break it down further. At this point my lack of education in mathematics starts to show. I suppose the easiest thing to do is also throw a d10 and if you need the more granular break down use the tens digit from the d20 and the d10 for the ones digit. That said most tables will break down into 5% increments anyway and even if you are making an opposed throw it will only matter if the dice fall on the same number.
I know most of us are very happy just throwing 2 d10s to get a percentile result but I'd love to find a way for Snowgen to also join the fun without having to parse the results of two dice most of the time.
My argument is that you almost never need more precision for gaming needs. A d20 will never be more than 2% off from a d100, and 2% is close enough for the game table (for me).
Proof:
| % Target | d20 Target | d20 % chance | Difference |
+----------+------------+--------------+------------+
| 60 | 12 | 60 | 0% |
+----------+------------+--------------+------------+
| 61 | 12 | 60 | -1% |
+----------+------------+--------------+------------+
| 62 | 12 | 60 | -2% |
+----------+------------+--------------+------------+
| 63 | 13 | 65 | +2% |
+----------+------------+--------------+------------+
| 64 | 13 | 65 | +1% |
+----------+------------+--------------+------------+
| 65 | 13 | 65 | 0% |
+----------+------------+--------------+------------+
| 66 | 13 | 65 | -1% |
+----------+------------+--------------+------------+
| 67 | 13 | 65 | -2% |
+----------+------------+--------------+------------+
| 68 | 14 | 70 | +1% |
+----------+------------+--------------+------------+
| 69 | 14 | 70 | +2% |
+----------+------------+--------------+------------+
You could argue that the extremes (1% chance and 99% chance) would be a 4% difference, but meh.
I did find this one blog post that I made in September of 2020 that said something nice about percentiles:
