floating point precision problem with ropping sub-frame

We just swiched over to 8.0.410, and I am seeing a problem with the rop output driver. I am writing out geometry at sub-frame (every .1 frames. When I run a range out (1001-1058 by .1), I see that the current frame starts to deviate by a small amount while it is ropping out. It seems to start out ok (1001 1001.1 1001.2), but quickly turns into (1010.19 1010.29 etc..) I am compenstaing for it by putting an expression in the frame naming (file_name.`round($FF*10)/10`.bgeo), but I am afraid that this might not be enough. Is there something I can do to fix this?

I am also seeing a proble in CHOPs, where I use the geometry CHOP to bring in sub-frame geo info (every .1 frames) and I see that the values in CHOPs don't line up with every .1 frames. Seems like the same type of deviation.

Any help would be great.

Thanks

Is the problem in chops to do with sample rate.
I'm presuming this would have to be set to a rate that breaks down nicely into your subframe steps.
