No! Don't stop doing these, they're great. I haven't had a chance to do exercises 3+ as I've been too busy, but I'm definitely doing these over the weekend. They're really useful in terms of actually having an overall strategy and exploring the relative merits and risks of any strategy.

One suggestion, once I've done them & you've criticised my responses, ie once I've really learnt something, maybe delete them all so none of my competitors will be learning too
