I started month before MI, playing about 10 battles a week (there were bad net in Poland that day).
Year later I was given better net and I was playing about ..... 10 battles a day (less into weekdays but more into weekends). I had very long holidays (cause I had good grades at university) and I was playing practically all nights. It was mtw1 and vi.
After rtw I was playing much less but its still about 4-6 a day and while SC had war with Wolves (2-3months) I practised only 1vs1 - 10 times a day again.
Into mtw 2 I'm playing less - it will be about 2 - sometimes 3 battles a day (I can not playing for 2 weeks and then im getting back playing over 10 a day - usually when i got tourneys).
All in all it might not be 10000 - maybe less. But not much less :)

I remember that when I was deleting logs it were always at least 20 mb :)
