hi every one, first timer on wafflepool

i just swithc from scrypt 2 days ago to x11 and i notice (if im correct) that x13 is more profitable than x11, i calculate this base on btc/mh/day on the two algoritms for the last 7days.

I open up a excel and put all 7 days profit from both and multiply by my own Mhash on both algos, but just realize i dont need to do the math, as the "vsLTC:" already does all the math right?

so can i assume i can launch my batchfile (one x11 other x13) depending the trending?
Last 2 days x13 vsLTC is way higher than x11 so can i just switch base on that every few days, or there is a better way, even a automatic way?

Also, as im new to x13 (3 hours  ) is the best parameters the same as x11?
