eh ???
what on earth "psychological aspect" to a record is there other than by the amount you think you can break it ???
i quoted herb as probably being worth close to 3'30 on '70s track based on fact his 3'35.6 was run on dirt & near solo with likely significant uneven pace
all that can certainly account for near 5s running on a synthetic track at even pace with some kenyan wabbiting him to the bell
as for his 3'54.5wr, so what ?
with standard 1.08 conversion it's a 3'37.1 time
