This pausing stuff is especially directed towards the cross.
When you're doing the cross, memorize what you are going to do, and execute it like an algorithm (this takes a lot of time to master.) So, you're doing the cross, and it's like you can do it blindfolded. So when you're doing the cross, and you're not thinking about it, because it's like an algorithms, look for your first corner you're going to insert (this works well if you do your cross on the bottom). Once you finish the cross, immediately insert the first corner piece. Then while doing the corner piece, (you already memorized the algorithm), look for another corner piece to insert, and insert immediately after you have finished inserting your first corner piece. Same goes for all the other corner pieces and edge pieces you have to insert. To get used to this, execute EVERY SINGLE MOVE slowly, and keep them steady. Then, while you're doing it slowly, you can look around for pieces easily. Then speed up your turns, keeping them steady, until they are full speed and you can look ahead fast (takes practice). You can use a metronome to help you keep every move steady. Keep in mine when looking for corners when doing the cross, it's hard to do it when you're doing the cross on the bottom. Edge pieces are easier because your finished side is on the bottom.
For the last layer, just recognize and execute your algorithms quickly. This will be achieved by practice. The more you practice, your recognition and execution automatically become faster.
Didn't you just create two threads that were about the same topic? How to reduce pauses vs. thinking process to reduce pauses. Don't do that.
