Hi Conrad I think a stand alone excel program or such might attract attention. I don't know about an add on to Vortex. Lichello's book has been removed in real form and is only being published as I understand it in e-form. Where will new aimers come from. ? Where will new vortex users and AI of mark hing come from? In U.S . we have various installment retirement accounts. I think an excel type program will succeed . Most people have excel would reach many people and draw attention to aiming. 1 step
