No, the question is how much more time do you spend training with a DA team vs. your own club team (apples to apples) because of the time HS takes away from training with your own club team. If you compare apples to apples, you probably train about 4 weeks per year more with a DA team than a regular club team. I would argue that 4 weeks or 1 month a year is not that significant.
Here’s my formula and please correct me if I’m wrong. DA trains for 10 months and a Discovery level team trains for 8 months (I’ll use our club team as an example), so that’s 2 months difference per year. However, DA plays 16-30 games/yr (based on Q&A from website), while we play approx 50 (league-12; crl-12; thxgvg showcsse -3; vegas -4; man city 3/4; surf cup-4; blues cup-3/4; scrimmages about 5/6). So that’s at least around 12-15 more games than DA which amounts to about a months worth of training (i.e. 12-15 practice sessions). So yes, DA trains more than a regular team but it only translates to about 1 more month per year, not 4.
Also for that extra month of training, a regular club player puts in 4 months of high school. It’s nowhere near as bad as people make it out to be, but it certainly is not DA. However, it is still touches on the ball almost everyday of the week.
So if there is a developmental difference, it’s not because of high school, it will be because of the difference in the club team themselves. If you train with a very good coach in a non DA team, you’re only training about 1 month less with your club team than a DA team trains with theirs.
Your formula is wrong. The DA SW conference plays about 35 games a year. Those teams also play in tournaments and scrimmage. Most importantly, you are counting weeks/months instead of days. You should assume two less training days a week. That's a huge difference.
