Can anyone make any sense of the numbers shown in the output?
I was following this guide on altering my touchpad sensitivity and naively thought there was going to be 3 numbers to deal with which I needed to increase The issue I'm having is the touch pad is far too sensitive. For instance if I slide across a tab as gently as I can I open up the tab or in drop down menus.
Unsure of which numbers I need to alter to make it less sensitive.

Perhaps you've solved the problem yourself already, if not, perhaps the problem is that it's not using the synaptics driver, that output looks like it's using the more generic evdev driver.

no not managed to suss this one yet although I've been that busy at work I've had to put it on the back burner. Is the evdev driver adjustable at all?

Obviously, it has those properties you listed, you'd have to experiment with the "Device Accel" ones. Is the xorg synaptics driver installed? Its man page says it works for any touchpad (that has a kernel driver), not just Synaptics ones.

My Linux allows a GUI config of mouses and touchpads; I don't have a touchpad - why not plug a mouse in?
For comparison purposes with the OP's output, my mouse says:-
Which looks basically rather similar.
