When to use advanced analysis

Greetings, bear with a newbie.
Are there any advantages to selecting “advanced analysis” when using recode 2 if the import says that 100% of the source data will fit on the target disk? Thanks.

i dont know about that one (i think it improves quality and space caculation a bit), but it only takes arround 15-20 min, so whats the harm

If 100% of source data will fit on target disc, then there is no compression, so the source will be copied unmodified on target disc.

Advanced analysis is intended only for compression, and, as referred by rssfed23, is made to improve quality.

Thank you both very much.
