Just a thought especially for new wet shavers....when I get a sub-par shave, given that most of my razors are in great shape, I can usually trace it to the soap and lather.
I personally don't need a pile of lather, but I've done it enough to know when it's wet enough to glide, but not too wet (and runny).
If the new guys will spend some time on the lather and the feel on their face (which starts with the soap or cream) you'll be surprised and amazed!
