My server generates webalizer reports every day at 00:00GMT, well, look at my generated report below, you may notice something odd with it

I have country resolving switched off, so all the hits should bee 100% unknown, but there is one odd value

Click here for my webalizer report

Look at the bottom table, there are three percentage values, look at the middle one, doesn't 100.38% seem just a bit odd to you

does not bother me at all, just a bit curious as to why it happened
