Using the visa refusal rate as an excuse sounds a bit like circular logic: "We're not going to give you online rubber-stamped visas, because we're currently not giving you many visas." I'm not saying that the refusals don't have merit, but since they are discretionary, the refusal rate may never improve. It's just the perception: "Those Eastern-Europeans seem dodgy to me, so we won't allow them because they'll surely overstay." Yet the reality is that they don't overstay so much.

Or do they have low levels of overstay because they are strict on visas in the first place?

Its circular indeed.
