Hmm let it go all night. Looks like it worked just doesn't smash out the accepted shares as fast as on the litecoinpool. Guess I expected it to be faster. And it successfully mined some sia, doge and dgb. Didn't expect it to switch coins but that's fine too I guess.
The rate accepted shares has nothing to do with how "fast" its mining. Its simply the difficulty the pool has set the shares too. Higher diff, less accepted shares, which is what pools want since their servers would be overloaded if everyone mined low diff shares. Higher shares have more "value" so you mine more litecoin.
Most pools use vardiff, so accepted shares are averaged to around 1 share per minute, regardless of wether you mining with a Moonlander or an L3+.
