1)Get used to to your letter scheme, possibly imagine that your cube is in your brain and you have got a hold of the corners and edges, for instance, corners, normally you would need to memorise 7 letters but if its less than that you should look around in your mind in case you have missed a new cycle. Also, once you are very familiar with your letter scheme, you will know which piece is included in your memo or not as you memorise through your cube,it just comes naturally. PRACTISE a lot, don't just do sighted solves or write down your memo it won't help much, you can at least do a blindsolve and if its a dnf, you can write down your memo and analyse
what have been missing or what is wrong with your memo and so on. the point is to push yourself further into blindsolving.
2)it's either there is an odd number of flipped edges/corners or you have not broken into new cycle(s), and it doesnt matter if your buffer is solved or flipped, if your cube hasn't been solved yet then it's wrong :X
3)No and never, and yes normally it would just be like as you have mentioned, BWVB but other than that is BWVG because the piece that is coming back to your starting piece doesn't have to be necessarily on B, because it can be the other side of the piece which in most cases its G(Im not sure what letter scheme you are using), so I highly recommend that you experiment things like these with your cube. Now, enjoy your blindsolving!
Forgive me if I have said anything wrong.
That's super helpful. So when the buffer piece is in buffer position but flipped when you first get the cube, you just ignore it, do new cycles, and it'll fix itself automatically?
Also I'm using Speffz so it would be B and M. (or BNQ for corner)
