Your observations are correct but only in a bull market. Corrective waves are always counter to the main trend, in this case we're in a clear bear market. Therefore, in a bull market waves a and c are impulse and b corrective. In a bear market waves a and c are corrective and b an impulse.
having discussed this with friends about this I am even more confused...as most said that after wave 5 the revsersal must not be lower/higher than wave 5...!!!
Apparently after 5 impulse waves the following 3 are corrective and therefore must form on the reversal side...i.e lower than wave 5 in bullish market and higher than wave 5 in bearish market...This is what most of us thought that must happen for correct EW count....you have confirmed that in your post..
So is there any refrerence you can point where this is explained more..???? as no reference I have confrms with your explanation..I have been scouring everyting I have in my libarary...
