no worries K. good scores in ranked stroke plays (tourney, match game, CC, ...) will decrease your AVP status every time when you have 'par' score or better at the end of course (9 hole - 35 or 36, 18 hole - 70 or 72). also, if you defeat player with higher tier then yours.
AVP 72 or less - wgt will improve you in Tour Pro tier, and your AVP will be 80. next time, at AVP 67 youll be 'master'. how many ranked plays you need to have for Tour Pro tier - i forgot that, around 50 (not sure). some1 else can tell you about that. you have good enough equipment. so you need just a little time to go up. good luck
edit: ouh. completion rate? forfeit or drop, when you want to stop play. never, and never do disconnection from the game - that is like escape without excuse and wastes time of your opponent. people dont like it and youll be yellow.
