That's no different than the U-95, the 1987 Cellular One or the 1988 Miss Madison as all three had pickle fork depth changes. They changed as follows:
U-95 was built with a 72" picklefork that was reduced to 24" in 1979
The Cellular one was built with a 120" picklefork prior to the 1987 season. It was increased to 132" between the 87 and 88 seasons
While the picklefork was the only changes listed on the first two boats, the Madison has had several hull configuration changes:
1990) Added shoes for a 14" overall length increase
1991) Picklefork increased from 112" to 126" during the engine swap from Allison to turbine at the Budweiser shop
1993) Length and width decreased by 1" when the sponsons were rounded off
1996) Picklefork decreased from 125" to 110"
2004) Canard moved forward and made into a one piece fully movable unit
2012) Cockpit replaced with the modern egg shaped style
