Not a comrade, but rather Mr, but will try:
Re 3 and 4 he said the following in his original tongue:
Teкyщee пaдeниe oчeнь xopoшo oтcкчит в paйoн 13000-15000 в кopoткocpoчнoй пepcпeктивe, гдe cмoгyт pacпpoдaтьcя тe, ктo зaкyпилcя пo мoeмy coвeтy, нo yжe ycпeл пpoкляcть вce нa cвeтe и oбмoчить пaмпepcы. Cливaйтecь тaм, пoтoмy чтo этo нe для вac.
Best translation I can conjure:
The current decline might very well re-bounce into the 13000-15000 region (short term), where those who bought on my advice [I assume his advice re buying below 10K], but already cursed everything in the world and peed their pampers would be able to sell. Dump there, because this is not for you [a.k.a you piss your pampers during the 10K-7.7 K move-refers to those who got scared].
Biodom, he is clearly referring here to his earlier advice to "ruthlessly buy" under 10k. I have been learning Russian for many years, but it is not my first language, so I am struggling to understand subtler points, and the Master likes to sounds mysterious at times

. So you think this "sell because it is not for you" advise does not mean he thinks we are going much down again after 13-15k, but is more an advice to the "nonbelievers" to sell there, not at the current bottom?
Re: wave 4. ML clearly thinks it is underway, says in comments it should take a couple months.
