If I had to guess, I think the match is equal to the lvl 4 training, not lvl 1 - this would also be true from Niko's numbers

Another point is that my players rarely lose 24% condition, more in the range of 18% - I think that's because I play them with low pressing, short passes, zonal marking.
So if you have a busy schedule, it's worth noting you can do stuff to lower their condition loss.

On the other hand, for the purpose of improving skills, if it's indeed equal to a lvl 4 training, maybe it's worth tiring them more, specially if you don't have access to lvl 4 drills (like me)
