it doesnt even matter...
as long as your non-defined blacks are below your black point and your non-defined whites are above you your white point, you can place your 18% or 9% or 72% any where you want; regardless of asa or EV.
For example, i'm shooting btzs and running at ev. so for positioning i can place my 72% or 4.5% or whatever wherever i want as long as i consider base black-point and white-point, easy peasy! but it's a sliding scale based on iso you say, so, i just jack the meter or my brain to compensate. it's still the same set of numbers, just slid up or down a bit twixt the ev scale, time and temp and stars being constant...
or is the fermented hops and barley working against me?
when i say "it doesnt even matter" im talking iso and keeping whatever ratios and meaning positioning relative to, of course.

It's not what is outside the printable range that matters, it's what's inside.

Second point, it does matter, exposure changes, change grain and other things.

yeah, but the ratios remain constant (and thats really the crux) regardless of iso exposure. so as long as i compensate for ev variance, either in my head or on the meter i'm good to go.

ok, im running at ev, so lets say my low ev is 9 and my high ev is 14. i can switch to any asa and measure my reflected values and use the readings as long as i keep the ratios and compensate TO my ev high and low.
as a placement method for reflected readings.
