Congratulations!
It's great to you see you having such great success after a long dry spell. You are lucky that you found out your REM times to be able to pull this off, as everybody's would be a bit different. This method exactly wouldn't work straight away for everyone, as people would have to find their own individual pattern for this to occur, but its really fantastic that you have fouind this out for yourself and hopefully myself and others can try and use this, as it seems like a really good method.
