Where are you getting your info from? Coinwarz show SBC more profitable than LTC.
Same place, during the period we were mining.
Sbc was at the top of the list before Hashcows started mining. Once a multi-pool starts mining a coin, the difficulty increases, sometimes by 2 or 3 times. The profitability is measured at the difficulty when the mining begins.
What you saw was the resultant profitability once Hashcows (and others) start mining. Happens every time we mine a new coin.
