I can not reproduce it though: until there is an estimate it just shows »Battery discharging ([percentage left]%)«.
And if the »(estimating...)« is how it is in fact done now, it should be changed to how Tobias was proposing in comment #1 and how I described above. If it’s estimating, it could mean anything; like you said it takes several minutes to estimate and therefore this meta-info is not helpful at all.
Sorry, that would indeed qualify as a paper cut.
