Like Pyrotex, I'm afraid I don't understand this. Acceleration is change in velocity. Velocity is a vector which means it can either change in magnitude or direction. Your table of data provides two different accelerations for one point. I don't know how to interpret that, and I'm very curious to find out how.
To help me interpret the data you could explain what horizontal acceleration is. I understand vertical acceleration due to gravity. On the surface of the earth if I drop something in a vacuum it will change velocity at 9.8 meters per second squared toward the center of the earth. If I give a straightforward interpretation of your data it seems I should be expecting an object to change velocity when dropped at 10.0604 m/s^2 in the horizontal direction. I doubt you mean for it to be taken that way because that would not agree with observation. So, I'm curious to understand what "horizontal acceleration" means.

I do not have power point installed at the moment.

After a good deal of effort engaging both you and Charlie in a respectful manner it's difficult to imagine how you came to the conclusion that I would like to 'be rid of you'. Your topic has now been moved into its own thread, here. The staff feels that discussion on your model is better-served having its own thread with its own topic. This will hopefully garner more useful responses. And, I assure you, has nothing to do with 'being rid of you'.
