Not trying to be mean but the 5* Peach lvl 70 200% = 25742
Evening Primrose lvl 80 200% = 26626
Difference is 884, so don't know where you got your information about her being close to a 6*
Considering Peach is basically a 6* in disguise (she beat Sakura/Mei prior to their buff), it's not an incorrect statement.
