The indication più 
in EF is probably non-authentic, same as which precedes it in bar 60. It is worth mentioning that despite the fact that the dynamic relation defined with those indications could be generally assumed as compatible with cresc. and in PE, the overall impression is totally different: the notation of PE is more precise in details (crescendos in bars 59 and 61), at the same time, it leaves more freedom by not determining the dynamics in bar 60; it also indicates the climax ( in bar 62) more clearly.
