Stormglass is a scripted solver with nothing to train.

Stormglass is a scripted solver, not a learned model: each level is a different algorithm, so there is nothing to train. Your match is recorded for your report and the board.

What is site Elo?

Site Elo is a strength number we measure by playing the levels against each other. Easy is pinned at 1000 and every other level is placed from its results against the one below. A gap of 200 points means the stronger side is expected to win about three games in four (76 in 100, counting a draw as half). It is not a FIDE or chess.com rating, so it says nothing about how you would score against people.
