Pools offer maximum rewards at 100% saturation, then diminished rewards after it. Daedalus ‘ranking’ isn’t very good and actually works against the chief scientists recommendations on leverage.
There are really only 3 factors that matter and Daedalus ranking ignores some of them.
- The pool is online and makes all its blocks, excluding orphans. This is, obviously, the most important.
- Current saturation - pools offer max rewards at 100% saturation. Higher the better up to 100%
- Pool pledge - higher pledge pools pay more rewards. Not a lot at this point, but they still do. It also shows the operator has skin in the game. The higher the pledge the better. A pool that saturates itself with pledge is the best.
Daedalus ranking is responsible for making the highest leveraged pool conglomerate, by ranking all of one person’s pools near the top, despite them being against network strength.
IOHK wrote a blog and made a couple videos warning against this exact conglomerate that Daedalus made. Don’t get me wrong, many conglomerates carry lower leverage than other single owned pools. So they’re not all bad.
You should look in a different place to determine a rank of your own. PoolTool.io, CardanoScan.io, and AdaPools.io give you the tools to make your own decision.
