ars told me this some time ago ...
MP used to train soo many hours for day and now he has to study and he can train only 1-2 hours for day .... he prefered to quit insted train such little time because he can never improve with only 1-2 hours for day ....
How many?
a lot

i remember once ARS wrote he did a total of 30 hours one week and usually does about 20, MP replied he used to train 50 hours per week in summer, going out to practice 4 times per day - even at night .. MP was also uploading videos from his night practices on Russian social network
it's not like he is super talented, i would say extremely hard-working and committed to freestyle
