I played this on PS2.

So I don't know what times to use for IGT, but apparently this is WR unless I've done something horrendously wrong? I don't know whether to use the full road trip times from all six road trips that the game calculated, or to add up all of the individual stage times because both routes yield different results.

By road trip: (55:55) http://www.grun1.com/utils/timeCalc.html?t1=4:39&t2=6:55&t3=9:15&t4=7:32&t5=11:29&t6=16:05&mode=0&fs3=1&ft2=1&f3t1=1&f4t0=1&d=:&o1=1&fps=

By each individual stage: (55:46) http://www.grun1.com/utils/timeCalc.html?t1=2:16&t2=2:23&c2=RT1&t3=2:16&t4=2:25&t5=2:13&c5=RT2&t6=2:19&t7=2:20&t8=2:15&t9=2:19&c9=RT3&t10=2:20&t11=2:27&t12=2:44&c12=RT4&t13=2:12&t14=2:27&t15=2:35&t16=2:16&t17=1:56&c17=RT5&t18=2:15&t19=2:22&t20=2:37&t21=2:15&t22=1:58&t23=2:27&t24=2:09&c24=RT6&mode=0&fs3=1&ft2=1&f3t1=1&f4t0=1&d=:&o1=1&fps=
