That's irrelevant tho, Excel isn't meant to be Outlook so why should it also be able to send email straightforwardly? The fact you're even able to send one thru VBA to me shows it is not "too simple for complex tasks", albeit probably ill-suited in this case (and many more, but that's besides the point). And while the calculator might be marginally faster if you exclude start-time, Excel is still perfectly fine for your use-case it only requires to type one extra symbol than the calculator, namely "=1024*436[ENTER]". Hell, it's probably faster to do it in Excel if you already have an active window. I don't see how it could possibly fulfill the task in a simpler manner. Is R a bad statistical tool because I can't use it as Photoshop?
