Yes, I think that is a flaw in the system. There isn't enough weight given to wins and losses. A 4.5 guy with a big serve and not a terrific return game may beat another 4.5 guy in a tiebreaker. He may beat a similar 4.0 guy 6-4, which would dramatically lower his level. He may lose to a 5.0 guy 4-6, which would dramatically raise his level.
If he is rated a 4.0, he would never be bumped up even if he wins all his matches and if he is rated a 5.0 he would not be bumped down even if he loses them all.
A 4.5 level consistent grinder at the same level as the above example may beat the other 4.5 guy in a tiebreaker, but beat the 4.0 guy 6-0, 6-1 and lose to the 5.0 guy 0-6, 1-6. He would quickly be rated properly at the 4.5 level by the computer.
