This is true - the dial is actually an accuracy dial. Setting it to 100 disables caching altogether and is most accurate and also most slow.

For some scenes, I can get away with 7, which is very fast.

I just want to pick up on this, please ...

If rendering with IDL enabled ( + using D3D's Render Firefly Script), lowering the Raytracing IC to a small(er) amount, but therefore incrasing the IDL IC, and perhaps the IDL Samples, is what would be suggested?
