Tracy, your points are well taken. To be sure, our best laid plans often don't work out. Where predation by natural predators plays a role, to be sure, one should plan for it in a put and take system especially. The plan serves only a baseline. If mortality turns out to be only harvest, and the harvest beats the plan, then one learns that his BOW is capable of producing more than he assumed. The same applies in vice versa. Many different insights may be gained by relating actual results to the plan.
In the end, the Spreadsheet shows what is possible when the world is as rosy as he planned. Even so, it can help one to plan and to prevent one from managing for an impossible goal.
