I get that the algorithm can't be disclosed but why is profitability going under LTC in the first place?
Shouldn't there be a fail-safe mechanism that jumps to mining LTC so profitability won't ever be below LTC? OK, never under 100% LTC might be too much but at least never under 90%.
I assume because you don't know profitability of what you just did till its already over. Between the time you decide to mine something till it payouts (especially all the way to BTC) there can be a lot of flux.
