The beauty of brewing... More than one way to slap a cat in the face.
It'd be nice to be able to do an identical side by side fermentation using a vial pitched directly and one made with a starter. Too many variables for me to pull that off though.
Speakin of kegs.... thats my next mission/upgrade. This bottling shit is for da birds!
Not sure I'm understanding this starter vs. no starter discussion. Unless you are going to check every vial's yeast viability on a slide, you will always be guessing as to what the percent of viable yeast is, no matter what the "best used by" date is. You can assume the best, or you can assume the worst regarding how the UPS driver, or retailer handled it.
Maybe you've seen this:

It works well, but it starts with an assumption as to what your vial/smack packs viability is to begin with. But, it's better than a lot of other options. Starters are insurance, and clearly, the better homebrewers likely Gordon Strong, Jamil Zainasheff, Denny Conn...will always use a starter with liquid yeast except in the most rare instances. Read Zainasheff's, and Kai Troester's work on yeast viability, and visit the AHA forum. Your work has just begun!
EDIT: I spoke with a biologist at Wyeast awhile back, and he pretty much disagreed with Zainasheff's yeast calculator. He assumes the best yeast handling, while Zainasheff assumes the worst based on actual samples he analyzed. A bit of a crap shoot, really.
