The idea is to create a baseline using the information we more-or-less know, rather than to guess based on hopes, fears etc. As we get more information, so assumptions change and the model grows in complexity.
I'd rather do it that way than just have a stab in the dark. If I'm wrong in a way I can understand, this will give me a chance to make it better next time.
By the way, my 97% growth in ESC-ETSL for this quarter (to $1-1.1m) is, I believe, the second lowest on the list of Wave's investors (at least those who have a sanguine opinion of Wave's future). All the same, I think my expectations are extremely bullish.
