Yes, that was sort of the crux of my question. The more space you waste the bigger the table. The bigger the table the slower your operations. But, joins are rather costly, so...
>As to the performance, I think the time it takes to execute a query will depend mainly on the number of records retrieved, and (especially for a not-very-optimized expression), the total number of records. But you might want to do some speed tests to confirm whether the total recsize() significantly affects the time it takes for a query, for instance.
Yea, I didn't want to have to dig out my equations, but I guess i'll have to do it anyway.
