One of the big uses of this for me is ore mining and then belts won't be full, or don't remain full when patches dwindle. Using the throughput seems like a bad idea.
If you have 2 belts you can always pass them through a splitter (to balance them) and then use 1:6 splitters on both sides of the train stop. So overall a 2:12 splitter.

Re: Perfect 1:6 splitter
I ended up finding the optimal 2:6 balancer of conventional balancing but didn't think it was worth posting since a 2 second search afterwards ended up showing its been found.
