Spark scene file from 150 to 40

[abeas]

It seems all of the scene file settings are identical (in terms of the values) on the 150 and 40, except for the Master PED. I believe the Master PED on the 150 goes 0-100 while the 40 goes 0-15. So I have all of the settings the same for the spark scene file on the 40 (same from 150) except the Master PED. The Master PED on the 150 is -2. So my question is what should it be on the 40? I imagine there is a simple math formula to figure this out, but my math is terrible, unless it involves simple addition.

Simple math would be 6.67 HMC150 clicks per 1 click on the 40. Not sure if the cameras actually respond at that exact same ratio though....

and if its 0-100 on the HMC how are you and I using -2... so is it -50 to 50 ? I dont have my 150 near to check.

Yeah it goes to negatives. Same with 40.

just do a few test shots.

I've done some test shots, and to my eyes, I can't see much of a difference. I know Barry lists the HMC40 equivalents to his scene files in "The HMC Book" so that's why I figured there was an actual number to make it completely accurate.
