Any ideas on managing multiple units in trading logs?

I was wondering what the best way would be to record trades in a trading log if I want to do statistical performance analysis and often trade multiple units. I may initiate with 2 units, remove one, add it back, etc.. I'm not sure how to match them for p&L and performance metric purposes. Anyone have a best practice on this?

a) decide whether to use FIFO or LIFO

b) decide whether you want to account for the strategy's P&L, the initial unit's, the add-on's, etc.; or better yet, track them all and then compare whether adding, partial exits and re-entering is adding value (not necessarily $$$, maybe just a smoother equity curve) or not.

c) Decide whether you want to track size as units (easier) or percentages of the account/capital (more accurate & useful, imho).

Good luck.
 
Thanks, I think I'd do LIFO. Do you know any software that does that sort of thing? I think that would be kind of hard for me to do in excel.
