I was told by an instructor that training dives don't count toward logged dives.
With the agency I was first certified in '93, (FQAS), we logged the OW training dives separately as training dives. So after certification, I started at 0 logged dives. The first years, it seemed to matter but now, who cares
As for answers given here, I agree that the log book is personnal and people can log everything they want although sometimes it's funny (I know a girl who logged a 10 minutes dive at 2 ft of water (no typo here), Really!!! It was open water she said :sigh

But it also shows that you cant really judge experience only by a number of logged dives. Experience is a cumulation of different experiences in different environments. Sometimes, you can learn more from a short aborted dive than from a 60+ min. dive at the same reef you've done 100 times.
Finally, I myself would not log swimming pool dives, but something like El Orans place (Nemo33), i would probably since it's pretty cool

My logbook serves me as a memory book since I'm not getting younger

and I like to write lots of stuff like my degree of satisfaction with a charter, any problems that occured, fauna and flora at different places and periods of the year. The technical data is downloaded from my computer also.
