These values are calculated based on a total tournament entrants count and your finishing position in the tournament.

Each of the 5 ranges is 20% wide of total entrants count.

For instance, if there were 1000 players in a tournament, places from 1000 to 801 are counted by Holdem Profiler and Top Shark Pro as Early finishes, 800 to 601 --  Early Middle, 600 to 401 -- Middle, 400 to 201 -- Middle Late, and 200 to 1 -- Late ones.

Normal values should be:

Early --  10%
Early/Middle -- 20%
Middle -- 40%
Middle/Late -- 20%
Late -- 10%

, so your results looks to be better than average.
