Same system as the WTA though it does seem to work better with the ladies for some odd reason..
SYSTEM PLAYS TO ADVANCE
FEDERER
ANCIC
STEPANEK
HENMAN
CORIA
MAYER/GONZALEZ * NOT ENOUGH DATA
AGASSI
GAUDIO
NALBANDIAN
FERRERO
H LEE
HRBATY ** DEPENDS ON WHICH SAFIN SHOWS UP 
JOHANSSON
LJUBICIC
NADAL/VERDASCO * NOT ENOUGH DATA w/ Roddick retiring
Well like i said previously system seems to favor the WTA for some odd reason but have decent result here as well
GL ALL will post plays as soon as i see some odds..
A few standouts though..
NALBANDIAN
LJUBICIC
CORIA
ANCIC
