What may be happening it the weight of tourists is tipping the island in such a way that you are always riding slightly uphill.
I have run it both ways, with and without the correction. Very little difference.
Probably not a tourist mass problem. The population of the island is 30,000 in season, but only 6000 during the summer. ...come to think of it about half of those miles were in tourist season...hmmmm.
