Hi jjv,
Drop me a note at 60e20f21@opayq.com and I'll send you mine which has a whole bunch more stuff than the original AIMbareS. I've added a Compound Growth Rate calculator tab, 3 different next buy/sell calculators as well as dividend and commission columns. All these help in backtesting a potential position. However, beware, backtesting is no predictor of the future, especially given the long in the tooth bull market that might become a big bear bite.
Also you might ask Tom - OldAIMGuy - for a copy of his version with Vealies. I've got a copy but since he created it it'd be best if he sourced it.
Best,
Allen
