I've be reading and speaking with some "ivory tower"(university) types, and there's an argument/suggestion for short sessions over time for true retention of skill(s). This has something to do with recency of training and how the human brain works. A short-2 to a few hours-with one or a few skills introduced, e.g., draw from secured holster, over days at medicated better retention. @
GJM has written of this related to flying whirlybirds and jets. So, a program could be a number of dry practice sessions over days finishing with live fire confirmation.
Now, this flies in the face of all that is holy in traditional firearms instruction: one to several weeks, immersion, regimented, etc. @
John Hearne probably has a good deal to say about this also. In my recent personal experience, I've seen noticeable positive results.
All this may be of no help to you, @
Whiskey, except to include in your plan follow along dry practice (please).
And again, get yourself some instruction and training if at all possible...
