Definitely doable. 8 weeks, it means by early May. Important is to keep an open mind when you try to read the market, be flexible and quick. Monitor, analyze, decide and act! 70 points, 8 weeks, these are only temporary targets, meant to guide you and meant to change.
Don't fall in love with your calls!

Looks like only seven weeks left-- hmm should I have given it more time than this? No, we'll stick with this call.
