Minimum value used for bin error

I've read as many discussions about binning and have not seen an answer to this following issue I am having with binning.

I have a measure that I'd like to bin and the data ranges from 4.1% to 13.9%. I'd like to create bins that are of size 1.96% to have exactly 5 bins (with unequal about of records in each). When I put this (or any) value into 'size of bin'' the resulting bins start at a value less than the minimum value for this measure. In this example Tableau creates the first bin to start at 3.9% instead of 4.1%. This is misleading that the data begins at 3.9% instead of 4.1%. Is there a way to fix this without a calculated field? If not, how would I create the calculated field in a dynamic enough way so that I do not have to figure out the minimum value for each of the 5 bins?
