This! 100% this. I loved phases 1-4. Then 5 hit and horror show. I realized quickly that I was building kludgy extraction routines to get the reports/metrics I needed. Once the horrible process became unmanageable I would have gladly paid the longer development/iteration time on phases 1-4 in order to have a robust and resilient system which allows proper reporting.
