W > AO/RG > USO for me.
7 Wimbledon titles would just be mindblowing. Double digit AO or tripple career GS on par and nobody cares about the USO anyway. It's not even considered a real slam these days.
If you win all 4 slams, all Masters, the WTF and one ATP 500 tournament, you'll end up with 19'000 points. If you reach every final of those tournaments and lose there, you'll end up with 11'500 points.
