The last part of his season scheduling may depend on his rankings, whether it's high enough to make the direct Aussie Open MD or not. If it doesn't look good, he would try to play as many tournaments(=5) as he can.
At this point,
1) Need 132 more points for 104th position
2) 52pts from the last year to defend
3) Based on the results in the upcoming tournaments, some of the current countable-lowests will be taken off : 8/8/10/15/15
So overall about (132 + 52 + 25~50) will be needed.
