I had a bit of fun with the tool and got this result:

Smart tool ... it may not be anything I would actually use but at least it figured out that this is a BAD recipe (though it didn't tell me why - not that I didn't know). On the other hand it didn't seem to take account of the 3 litres of cream of tartar I chose as a leavener! I have no idea what size serving (unless I do my own math with the # of servings in x # of grams) is but hey apparently it is only 31.46 calories per - so (aside from the fact this would be totally unpalatable anyway) it is great diet food (for a carb based food) I would say. 
What does it do with the information one might put in for hydration? Just for fun, I told it 125% hydration (but why am I asked to then give that a 'measurement' as well?) but that wasn't even a possible 'request'/desire given that I only told it 1 Tbsp of heavy cream and no other liquid (although I guess if one doesn't drain the zucchini after grating that might be a bit more of unspecified liquid-ity.
As to how I create recipes, that mostly happens through evolution (making a similar dish many times over the years, often when I don't have all the ingredients on hand) or sometimes I read a lot of cookbooks for 'ideas' and basics and then (without a specific recipe in front of me) I just start dumping into a bowl till the mixture or whatever seems the right texture (and I taste as I go along too - even at the raw stage if that is safe). Yes, I fail sometimes (but that is how I learn) but I have far more successes. Unfortunately though I rarely make exactly the same thing twice.
