Clarification using _MEM

[SpriggsySpriggs]

The OFFSET is the location of the MEM block. The SIZE is how big the MEM block is at that OFFSET. Think of OFFSET doing the same thing as _OFFSET(yourMemBlock). You could take your current position and subtract it from the size to see how much you have left. If the offset is 62349, for instance, and the size is 32, you can know that 62381 should be the end of the MEM block. I'm probably not explaining this coherently, but I hope it helps a bit. I don't think size is supposed to be marked as something that changes. That might be a typo.
