My 2 cents.
Considering the speed & vehicle differences we have now compared to when LSR started, this would seem like a good idea but changing the parameters to make it easier would be an injustice to those who previously "broke" an existing record on one trap in one hour in both directions.
Back when SCTA changed from return runs to next day down runs it created the same situation & I thought at that time there should have at least been a line drawn through the record book showing the difference. As in those guys did it down & back within one hour but these new guys went back to the Motel, got a good night's sleep & put down another one the next day.
There were times back in the "return run" days when we were a red pussy hair from 400 but missed out on the record because time ran out by a few seconds.
Don't get me wrong, I totally agreed that the end of Bonneville return runs due to the lack of salt was the correct decision for safety especially after Nolan ran out of real-estate coming back toward the freeway.
To me, changing the rules/parameters you wouldn't be breaking a record, you would be claiming a record, just like Mickey Thompson Challenger, The Budweiser Rocket & the American Eagle.
