Drag Factor Conversions

[[old] nharrigan]

Do any of you know a way to convert the damper setting on a model C (PM1) to the new drag factors on the model D. <br />I've been training on a Model C at a damper setting of 6.5. Recently, I tried the model D and had trouble setting the drag factor to the right resistance. I know dust and other stuff can affect this, but if both are clean and away from walls, etc. what is the relationship.
