As you can see oldest token is 18 days where uโre querying 3months. /ga 1mo will probably show you more tokens.
On longer timeframes, there are more aggressive filters (because Rick does include everything, there are no call/gamble/just scanning buttons) to ensure quality of the leaderboards.
From your example it looks like you donโt use Rick for a very long time, so it makes sense that 3mo does not include this many tokens. Overtime, this should improve a lot.
You are right, with for example 80 D many more things appear. I have a test group where I copy many things that I automatically scrape and there I was testing it. Although I donโt understand why some of the best calls, such as MAX, donโt appear when there are fewer results (a few more days).
Because if you query 3 months, we expect that a token is at least scanned a few times in the group. The thought here is that if this didnโt happen (no one ever checked price again, no one cared, no one was in), this token is considered not relevant over a period of 3 months thus itโs not included.
