Mine the round.
Low runs one worker at half duty, medium half your cores (or 60% GPU duty), full every core but one (or the GPU flat out). Mining uses real power and heat; on a phone, low is the sensible setting. Auto submit asks your wallet to sign each time your weight improves, at most once per 1.5 s burst.
Each finished practice round adds a core.
Each submit is a Solana transaction and pays a network fee (about 6,200 lamports with the priority fee this site sets); your first submit also pays about 0.0015 SOL of rent for your Miner account, which the program keeps open for your later rounds. Results are not guaranteed: the pot depends on trading, and others may hash faster. Calibrate checks that this device computes the same hashes as the program, and measures its speed.
