Why 37? The chart above calls for leaving NP at 92% and arriving Brighton 45%, so 47% difference. Extra 8% at the first stop gets you to Brighton at 53% (100-47) but then only 6% back at NP (53-47).
All assuming that it's symmetric - which it probably is more or less for this route.
You are correct. Brain fart on my side ! Apologies.
