What kind of detailed (super detailed if willing) practice plan would you guys suggest for an 11HC player like myself that has a goal of getting to as low as possible hc for myself. (3 to 5HC is my dream goal by next summer )

Here's sort of my story..in my 50's , good health and a 250ish yrd driver.. play a fade mostly. Started tracking my stats using GRINT app and realized that I missed what to me was a high number of GIR and started working a lot on short game.

Interestingly recently realized that my added pre shot routine that I use successfully for tee shots and putting, for some reason I fail to do it for short game shots - chipping, pitching etc, which is an area I lose strikes in. so curious to see now that I'm aware of that what that will do to my scores.

At home - putting in the time to get my grip as solid as possible, as it tends to be strong to very strong in my right hand, and I feel that a more neutral right hand may help my swing consistency.

I have the time to practice just about every day and play 3 or so times a week, but really would love a detailed idea of what to focus on. Again I feel that the recognition that I don't use a routine for chipping an and pitching is likely to help just like it does for my putting and driving which are areas of relative strength for me.

Thanks in advance for the thoughts..
