Under the old system, got to 4.5 just before I got married 33 years ago.
Under the new system I got to 3.3 in Feb 15, currently 3.5 with the next flag not dropping for another 7 rounds so a good chance to go lower.
Would love to get to scratch but at age 59 it may be beyond me!
Other than that the next goal is to shoot my age, realistically still around 10 years away.
