Radial scale offsets object

Gordon, I couldn't verify the problem. Sorry.
I think that can happens when you are scaling for a high values. In computer math this small difference can appear because of the way floating-point works:

Code:

So you’ve written some absurdly simple code, say for example:
    0.1 + 0.2

and got a really unexpected result:
    0.30000000000000004

You can try to use the Tools->Bounding Box->Bounding Box... and create a bounding box with the exact dimensions you want. Then you select your entire object and use Tools->Bounding Box->Scale To Saved Bounding Box Proportionally->All.
It probably will give you the same result, but you can try to see if it doesn't.
