I have not read the book, but the Article in Investors Chronicle was excellent - so I have shoved it in Wheelie’s Bookshop on the WD2 Website - find it here www.wheeliedealer2.weebly.com
I also found the Chart below on Page 28, and I thought you lot would like to check it out.
I hope the Resolutions are ok - I couldn’t do a direct copy (funny that?) so had to ScreenScrape them,
Pinch on !!
