Changes during Design Review

Hi, We are currently responding to LEED Reviewer comments for a building. We have 5MW of PV on site which is not pre allocated so we allocated what was required to hit the points we needed and got a letter from the client (this was accepted by the reviewer) However It is looking like we may lose a credit elsewhere and the team wants to increase the amount of PV allocated to offset this so we would resubmit with an extra point....is this valid? It raises my eyebrows a little but i can't actually pin point whats wrong with it or see any official guidance against this (technically the client could more available than they first thought for this project so it could be seen as a design change but then perhaps that would need to be done at the construction review). I am concerned the reviewer may have other guidance and will have grounds to reject. Thanks Victoria
