If by “statistics” you mean first observation and last observation, those were the reason for phasing out checklists – the database had a very hard time keeping up with those fields.
If by “statistics” you mean the bars on the right side of the page, I’m not really sure what you’re missing from the stats view on the project page? You want the data from the unobserved species or something else?
