I think it would be acceptable to decide on a max amount shown on the voting slider. The estimates are starting to become more accurate, and I now introduced a change in scot so that payouts algorithm takes into consideration recent votes (this won't make much sense unless you know how the hive mechanism works, where it adds to 'recent claims' the voting weight of posts that are paid out, and payouts are relative to this recent claims number * reward pool. This recent claims number decays over a period of 14 days or so, and is what allows it to adjust to active voting behavior on the chain over time. However, it is not a good setup for the bootstrap phase, and I found out while digging that the initial way pending claims worked in Hive bootstrapped by adding new votes to this recent claims up until a hard fork that stopped doing so)
