estimated · possible · preferred
Why
An unelaborated prior phase4 row proposed 'July 22 probable' but shows no arithmetic in this packet to verify; not adopted.
Reasoning
Both radio talks that announce this coming Sunday lecture are dated July 1951 at month precision; the independent chrome/live-text datelines on each node give possible/circa confidence at that precision (the certain catalogue claims are backfill and are not used to raise it). Since neither talk gives a day-of-month, the Sunday itself can only be placed in July 1951, not on a specific date.
