I understand it perfectly, repeatedly saying I dont will not change that.
WEP in AH has nothing whatsoever to do with water injection, breaking wires, using the extra indent or whatever. It is merely the name used in AH to describe a modelled, single, maximum power setting which is time-limited.
most engines had multiple time-limited settings, and HT has generally done a sensible job of fitting these into their single setting model. the 1820s, merlins, allisons are all pretty easy to fit into this model. typical sorties in AH are short enough for the longer limits to be treated as continuous settings. if you want a really tricky engine to model with one time-limited setting have a look at the Ju88 pilot notes.
the point stands -
the Brewster could only use its maximum power setting for 5mins. in AH it is allowed to use this setting continuously.
the eg. Spitfire could only use its maximum power setting for 5mins. in AH it is allowed to use this setting for 5mins.
the brewster is not modelled consistently with almost every other fighter in AH.
dont get me started on buffs
