I know CHK has had this conversation with CricHQ regarding their DLS system on their scoring app - some HK based mathematicians/scientists offered to help collate date for the algorithm so that we have different DLS calculations for different age groups and mens/womens cricket. The scoring patterns in Men's T20 does not match those of U13 T20 or Women's T20. For example - a men's team starting on 60/0 in 6 overs could likely post 200 in men's cricket. The odds of U13s or Women's posting 200 after the same start is significantly less, because in those leagues a 60/0 start is a freakishly good one, akin to a 90/0 in men's T20.
What some of you seem to be unware of is that DLS calculation is not some sort of progression algorithm which assumes a team will continue on at the same rate that it started. It uses past results to determine a likely outcome:

This is why you should have different DLS systems for Women's, Juniors, and I would argue even Associate cricket. The scoring patterns are not the same at all.
But, as StephenZA has pointed out, this is probably already being done. I have played around with the ICC DLS 3 software and they do have different algorithms for 50/45/40/20 over cricket, but i don't recall seeing a different algorithm for women's or junior cricket.
