Bingo--I started one just like that as of last year, however, I break down my data acording to stands--my spreadsheet serves 2 purposes, oneis a stand predictor (I made it just out of curiosity, to see how closely where I decide to hunt corellated with the known factors of wind speed & direction, temperature, time of year, AM vs PM, precipitation andbarametric pressure. I use a simple algorythm to calculate the most worthwhile place to sit on a given day's conditions based on a probability, stand 1 might be .85, and stand 2 might be .62, so i would pick stand 1.....much to my supriseit coorelates quite well with what i decide as to where to hunt.

the other half of my log I record everything deer sighted, type, hunt conditions etc. I do not have enough data in it yet, but my plan is to use the data gathered and refine my algoryms--for instance right now winddirectionis weighted 3, time of day and year 2, wind speed 1.5, temp & percip 1 etc.
