You are complicating it. All you need is a rough idea so that you know if they have enough stores. Within a few pounds isn't going to make that much difference.
You are probably right if all you are interested in is whether colony "a" has enough to survive the winter. However, if you are interested in comparing a number of colonies to see which of them are more frugal with their stores and how they build up the following spring (i.e. identifying colonies which can do more with less) so that you can include this information in your selection decision, I think the information is important
