If there are relevant economies of scale then they would be worth capturing in whatever period you are donating. Restriction to reaching the desired scale through investment returns by the desired time periods would rule things out for most small donors and belief sets where it matters, so I think measures like donor lotteries or derivatives would still add value if one expects increasing returns.
Donating every few years from one’s DAF in larger increments makes sense to me, but on a 10 year time scale you could miss out on the expiration of low-hanging fruit as funding in relevant causes becomes more crowded.,
