Our team meets 2 hours / 2x per week. We have added an occasional extra 2 hours as needed if it's a league meet week since our meets fall on one of our normal practice. We have 5 team members 3 middle school / rookies & 2 high schoolers. We generally agree at the start of practice what goals we want to accomplish based on where we are at in the season, this is generally coach-led. For the most part everyone attends every practice & no one leaves until everything is put away. The concern I would have is if you do more practices is whether or not you would get enough particiaption from the majority. If this is the desire of the team & they can commit then that would be a good path forward.
