I get it’s unlikely to change.
But Ted Williams had 185 hits in 456 ABs that included 14 run-scoring flyballs.
In 1941, this resulted in a .406 BA.
In 1940, this would have resulted in a .419 BA.
In 1939, it’s .406 again.
In 1943 through 1954 - .406
In 1955 and since - .419.
From 1908 to 1931 - .419.
Before 1908, probably higher than .419 (prior to 1908, hitters were not credited with an at bat if any runner advanced on a fly ball).
That’s just some weird rule changes…
