1) Learn how to use calculus, or spreadsheets. PLEASE save the reader the burden of ploughing through several pages of your long-hand calculations. Your method of approximation by small intervals is the introduction to calculus, or finite-difference numerical methods. At the scale of increments you're using, it's not precise enough. You need to do better, or do it simpler.

2) I will continue to delete long rambling posts full of calculations from YOU, or anyone else.

3) If you have a cogent point to make, make it succinctly.

4) If you need to refer to extended calculations, use an external website and link to it.
