I think some people miscommunicated when submitting values. Rather than mentioning the level they were upgrading to, they mentioned the level that the buildings are currently.
Ones I can confirm are
lvl 7 to lvl 8: 175 crests (rather than 300), 17.14b/plate
lvl 8 to lvl 9: 300 (rather than 500), 16.67b/plate
Presumably, the same thing happened for upgrading to lvl 10 and 11 (lvl 10 500 plates rather than 550, and lvl 11 550 plates rather than 600), though I can't confirm these atm.
