Yeah, the SP requirements for breaking the dust limit are really a bit crazy these days, but I also don't expect that to change for the better in the near future.
Steemworld.org is an amazing tool, one of the best, especially when dealing with things like the dust limit, it's one of the very few interfaces that allows customizing the number of decimals in the settings and see the voting values conveniently and without rounding errors!!
You're a supporting user of the bunny, so please don't hesitate giving the occasional dustvote when you're short on SP, the bunny definitely treats you with enough priority so that you should get it fluffed up reliably, at as long as there's not too many of those coming in a short sequence!
