Yes it's wrong - Table Stability a.k.a. tiConsistency in Delphi, is a totally exclusive lock that has virtually no application in real life except, maybe once a year, to freeze an old-style inventory system while processing stocktake reconciliation reports. Use Snapshot (Repeatable Read) isolation (tiConcurrency in Delphi) for reports.

That's exactly what Table Stability isolation is intended to do. It literally freezes every table on the system that is touched by that transaction.
