I assume that your title is meant as a takeoff on the fractals business. If so, congratulations.
While your hours count seems in the reasonable realm, I have always mistrusted statements of how many hours one has in a project. From my personal perspective, it is a meaningless number in the absence of details as to how it was computed and exactly what type and level of effort went into each hour. These are details which are tedious, and difficult to get interested in. One's technique, materials, and machines might cause many "building" hours to be spent sharpening tools. One might spend a considerable amount of time studying plans, and then planning the order in which to do things. There is time spent in ordering and gathering up what will be needed for the day's planned work. Then there's oiling, and measuring, and fitting, and fixing errors. You could argue that such things, and many more like them, should not be counted in the hours total, but how can you not count them? Noone goes into the workshop and just turns on a machine and bang, the chips are flying in minute number 1. Among other variables is the matter of experience. Those of you who are old hands, with lots of experience under your belts, are liable to log more productivity in an hour than others who are nearer the beginning of the learning process. The same sort of variation occurs with respect to what is a "finished" project. For a master craftsman, the number of total hours in a project often sounds like a pretty big number, but one reason for that is the time it takes to get to the level of detail and perfection that has become his standard. Those just starting out, on the other hand, are likely to declare victory at an earlier stage of completion of the project.
Sorry to be so long winded about this, but I did want to get across the notion that, to me at least, hours should be the last thing to attach any importance to. The important things are doing the best you can on every job, learning how to do it better, and then doing a better job the next time.
