What you miss is that the two passages are given at different points in the chronology, with the 800 at a later point than the 300. So, both could be accurate.
Personally I tend to think that the numerical differences are more likely due to copying errors which have no effect on doctrine. But in this case, you don't even have a solid numerical difference due to the time factor.
