Hmm, fascinating debate...
Walkersworld, I'd be a bit careful about using words such as "criminal".
There's a difference between how things are reported to the taxman (if indeed this is required), where things have to be done to one particular set of rules, and how one uses statistics to assess one's own investing performance. With the latter you are at liberty to use any method you like.
It's similar to how companies report their financial results, where there are "statutory measures" which have to be done and done in a particular way, and "Alternative performance measures", where companies can also choose to present figures in ways of their own choosing. As long as they state clearly which are which, is there a problem?
With my own share dealings which are outside my ISA, I follow the HMRC method (currently called the "Section 104" holdings) with my spreadsheets, simply because I only want to run one system, not 2 different systems in parallel. If people also want to run their own system, for whatever reason, where's the harm in that?
Mike.
