Guys how long of practice did it take you to have an average of 4 LD/ month (throughout a year)?

I'm trying to practice LD since I was 20. Now Im 40. I have been on and off practice many times in my life and now it's been since 4 months ago that I started and covid quarantine helps. But still the last month I've had 0 LD and the previous one 4 LD.
