Hi Little John,
Thanks for your suggestion as I think I can do that

I did see Michael Bush's page regarding cell counts on various Langstroth frame size so can refer back to that after I do my calculation.
Regarding your question as to why - one reason was simply to have a better understanding as to what is going on in my top bar hive regarding egg laying from the queen (i.e. how productive is she, etc.), expected future brood to emerge, and so on. The second reason is just trying to relate information I read and hear about Langstroth frames to my situation. After doing the calculation, I will be curious to see if my frames approximate a deep frame or medium, for example.
Again, thanks for your suggestion.
Kevin
