Needless to say that if your lather is too dry and you add more product you will compound the problem and vice versa (hydrating the lather when you have too little product). I said that it is really one because the soap : water ratio is just not right. Different products have different product : water ratios and you may have to play with it to find the one that works best for you, MWF seems to take a bit more water than others. Another thing to consider is how long it takes you to shave, if it takes too long, the lather could go bad before the shave is over.
Both excessively wet or dry lather can surprisingly have a similar appearance. If you go too far past peak (the point where no more lather can be built), the lather would vanish into thin air. One thing is for sure, it is better to use a bit past the point lather than dry lather. How do you know if your lather is dry? put a little bit of lather on your thumb and touch it with your index finger; then separate the thumb and the index finger slowly and see how long you can go before the lather breaks. You should be able to go about 1". I call this the inch test.
I think the advice you have received so far is great but I would not recommend using so much glycerin in one shave, perhaps 3 drops max, and I reiterate, I never had the need to supplement my lather with glycerin when using MWF. Glycerin is a humectant because it helps retain wate but adding too much can lead to dryness of the skin. Also, although I am an avid face latherer, and also a firm believer that one should not switch lathering methods until the first one has been mastered, I think that bowl lathering is the easiest way to determine the soap : water ratio for a particular product, as you have better control of the variables.
