Tracking BB/HR Question?

[Pot Luck]

I have been keeping indiviual records for my results at various limits. .5/1, 1/2, 2/4, and 3/6. From these results I have been calculating overall BB/HR and BB/100 etc....

My question is, how do I account for time at NL and PL SNG games and Single Table Tournaments in my overall numbers?

I suppose it is only relevant to track if I am making a profit or not at the Single Table Tournaments and would not want to weigh the results into BB/HR etc.. but what about the SNG games? Is it fair to weigh my wins/losses from PL and NL sessions in with my limit sessions to calculate an overall BB/HR?


Thanks for your thoughts.
