Not necessarily - too many interrelated, interconnected and potentially conflicting factors.
Both my F3 and an old Fortec Star box I had, for instance, would actually cease showing an increasing reading with more refined alignment but then the reading would suddenly drop back to a fixed value. The Fortec Star showed 64 (Yes indeed) under near overload conditions (AGC working flat-out). The F3 shows around 88, IIRC.
It doesn't reliably follow any consistent rules.
That's why Receiver Metering should be treated as little more than a guide. Useful for alignment and useful for detecting when things are getting out of kilter - but only by reference to what you noted the figures were earlier in time.
A separate Professional Meter is really the way to go for those needing to ascribe meaningful and consistent figures.
