Ah, of course CS, a sky-god like you *never* gets caught out by unexpected weather...anyone who does must be a mere pleb. Your arrogance is astounding.
I hope the numerous studes who are evidently in awe of your superior state of being are not led in the direction of complete inflexibility that you seem from your posts here to be advocating.
As for IO540 and I, I suspect we'll both stick to our own, carefully thought out, instructor-advised, and experience-gained ways...
