Yup. Ignore the lather photos mega thread. This may be the single most "disinformation laden" thread on this forum.I know this was a quasi humorous post, but just in case OP missed that, I want to mention that if lather can stack like that and the peaks hold their shape, like shown in the picture, then it's extremely under hydrated.
One great tip was posted above. When bowl lathering, periodically feel how slick it feels to see if you overshot your hydration (the other extreme).
