Here are my 2 tips, from a guy that has water so hard that the rag next to the kitchen sink becomes like cardboard after it dries.
1. use MOAR (more) pruduct. I find that the almond sized amount recommended simply doesn't cut it some times. And it's no big deal if you end up with enough lather for another pass at the end of the shave. If anything, it will help you dial in the amount you need.
2. While re-applying for another pass lightly dry your face with a towel, so it doesn't add too much water to your perfect lather. I have found that the amount of water on ones face can ruin a lather and water it down.
