think I will try that^^^ I mixed 500k with 1 mil.
Yeah, I never seen 700k myself.
Mixing is ok.
But it is a rough approximation, that can work.
I could have went straight from 500k to 1 Mil. A big jump ...
But I don't like to overshoot diff Oil cst.
I work my way up a little at a time., evaluate from there.
