Hello everyone! Greetings from Argentina!!!
I am new here and this is my first post. I have a question that is creating me a lot of confusion:

If i play 1 spot or 2 spots with 75% bet each, my RoR should remain constant. I use powersim to get this info and so far so good.

Yet when i go to qfit calculators and it asks me for EV SD and hands played , i dont know what to introduce here. For 1 spot is pretty much straight fwd but what happen when i am trying to find the answer for 2 spots?
As i am betting 1.5x wager per round should i introduce a 1.5x EV and same variance? Should i keep same EV and variance but increase number of hands times 2?

I want this info to calculate things such as probability of reaching a target or actual results among other things...

I hope my question is clear and hopefully somebody can explain it for me.

Thanks!
