How much of the token's supply have its snipers held, over time?

On SOL, the share of supply held by the wallets tagged as snipers (wallets that bought in the first moments after launch), as a series of change points: each point is the share from at on, until the next point. Points are irregular (on SOL at most about one a minute), oldest first. A token with no sniper series answers points: []; that is a real answer, and when the series cannot be read the request fails instead. Pass from on long-lived tokens: without it the whole history is read and only its most recent 1,000 points are returned. On RHC, for tokens launched on one of the chain's launchpads only (any other token returns 404): the snipers are the wallets whose first buy came within 30 seconds of the launch, read from the chain, and a point is every second their combined balance changed, so there can be several a minute.
