My best result is wining 1 game so anything I do will be better than my past results
Your best return is 1 point and you want to know how many you have to WIN to get into French Open Qualies ? I admire your ambition but this sounds highly unlikely . Josh Goodall has won 7 10k,s 1 15k and been in 2 15k finals. And he,s still not certain at about 227 in the world. If your serious you should try aim at getting 2 points first never mind getting comfortable at that level !
