Hi there - It definitely sounds like tracks are the best solution for your use case. +1 from me as reviewer, we need to wait a few days for others to chime in at which point I’ll check again and maybe action this request.
That said, I would create only 0.27 - we don’t typically create tracks in advance, however once your first set of tracks is ready, you can simply request more as needed here and per Simplified track request process for snaps with predictable cadence we don’t need a waiting period, we usually create them pretty quickly (I can’t provide a concrete commitment but I do aim to process them within one working day and typically create tracks “on sight”).
