Welcome aboard. They are all good questions but for me it is about the ability to brew consistently and timely.
I enjoy a greater variety and better quality beer because of the BM.

If you what a cost benefit... It's the time a 3v takes. I used to find out took all day and sometimes some of the following. The BM takes 5 hours and most of that it does on its own.... I am free to get on with other stuff and only have to wash up one vessel :-)

1. the pump pushes the grain up against the top screen, which can slide up or down along the post. so when the grain pipe is not completely packed the grain bed is still set upside-down at the top, and the wort runs very clear like a well established gravity-fed grain bed. the difference is that the final lautering is done by gravity in the reverse direction, so the bed sort of has to re-set at the bottom of the pipe. therefore you get some particulates in the kettle, but really not very much. if you want to run completely clear wort to the fermenter you just need to settle the wort after the boil, which of course you would do anyways. in my opinion it's a total non-issue.

2. stepped mashes, there are countless arguments on the topic, and everyone has an opinion, some supported by facts and others not. so i won't touch that. but there are certain grain bills; high percentages of unmalted oat or wheat for example, that benefit from various lower temp rests like beta-glucan and protein. also i love to do overnight mashes, with relatively normal sacc rests and extended mashout, this requires an automated stem mash while i'm snoring away.

3. about 5000 years

Youtubing Braumeister stuff to "train" the use of it while my Braumeister is being replaced by Speidel due to some rust issue, I found this video.

It somehow relates to the Bottom up vs top down topic. Seems that the guy on the video, inverted the pump flow to have the pump sucks below the malt pipe and overflow the malt pipe from the side.

I do not mean that it should be the way to do it, just found it interesting enough to share it as I could find it on the forum.

lower efficiency of 3v? guess that depends on what 3v setup you have, but most i've seen are certainly higher
