I took it to mean that it was a strong record to break, not disparaging its length of having it.
(For example, my buddy Steve Batchelor's C/Classic Fuel Altered records of Bonneville at 243 and El Mirage at 213, both set in 1992, ain't an easy thing to surpass, now 30+ years in the book. Looking at the B and D records in those categories will confirm that. The El Mirage record surpasses both the A and B records.)
