totally new to this.. been mining for a week or so, works well and easy to use! I'm using the "Legacy" version, read somewhere that it gave somewhat better results, its my (very limited) experience as well.

since 18h or so back the rate has dropped with around $1/day.. is this normal? it was on a steady $5 since start, now its around 4. I guess the value of everything just dropped or perhaps the difficulty increased? Again, totally new so i have no idea what i'm talking about  

I did the benchmark again (i always do the "long" one), is the benchmark for selecting what is best to mine currently - so it needs to be done every now and then?

i have a i5 8600 (@4.6) + and one 1080ti.
