Elena has 7 1st round losses in those 28 tournaments. So those 7 events have not contributed to her total at all.
Plus isn't it your best 17 events? In my eyes Elena has played 21 solid tournaments (even some of those were up and down), but she didn't go deep in a lot of them, its only since April and especially the hardcourt circuit that Elena has kicked on.
Elena has always stated she needs match rythmn and needs to play regularly to keep that rythmn. Plus with the EOYC coming up, I think she is very motivated to make it (and increase that ranking too).
Just don't overplay Elena!!
