As far as the results go, we figured that users would want to see how they can break up their deposits across multiple accounts to maximize the yield of all their deposits. So putting 1k in DCU may be pretty nice for someone with 3k, since that 6% is a massive return on what's effectively a risk-free product. For someone with more savings, I could see how that drop in the bucket is pretty insignificant, and could probably be filtered out.
A common theme of the early feedback we've gotten has been "add more filtering," so it seems like it'd be good to have a way to limit the results to only the best single account that could take the entire balance. We'll work on that.
Also, thanks for the heads up about HMB and OF. We'll add those later this week!
