Talk:RR3 Wiki:Upgrades Strategy For 100% Completion/@comment-2405:204:B185:8100:ECDE:8EF1:954E:3BC3-20180714115017

I don’t understand the ROI mentioned in the ES section. For e.g. the Performante requires 619 GC to FU. 29 GC is received from its 100% series completition & 80GC from its ES making it a total of 109GC in returns. Even if I take into account the 70GC from its SE, the total comes to 179GC. So how is it marked “YES” in ROI?

Where are the additional GCs to recover the upgrade costs coming from?
