some months ago (in January) for the project i collaborated in there was a quite evident increase on the code lines amount, which wasn't actually done) and strangely at the same time i was attribuited almost 250k lines of xml code which i never wrote. Now the additional lines have "reduced" but the 250k lines in my profile are still there. if you compare the median lines commit with the amount of months 15*607 it does a bit less than 250k ;)
