Limit point analysis explained

I made this back in 2009 as I started my career as an ADI. Back then my camera, editing software and editing skills weren't what they are now - but the message remains the same. On my original channel it reached over 50,000 views - none of which counted towards monetzation :(
In the interests of road safety I've made this available to share.
When time permits I will make a more 'polished' version.
