I have always shied away from T-shirt sizing, because I want to be able to compare relative sizes mathematically. How many "small" stories could we do instead of a single "large". Fortunately for me, nobody on the team pushed for T-shirt sizing, and we agreed on this number system as a group. Credit to Julien for proposing the basics, which the team tweaked to produce the posted result.

Phabricator does allow string entries in the points field, by the way. I just don't like them. :)

I look forward to the next several weeks, when we should start to be able to measure velocity and refine the estimations.

\o/ This is awesome! At my last gig, we started using "t shirt" size columns (small, medium, large, XL) when we had a couple epics worth of stories to point. It was much easier to keep a sense of scale when sizing stories next to each other. Each story card would land in a size column and there would often be some column adjustments in the process, "how could that possibly be a 'medium' when this is an 'XL'???" On the Android team, I know we generally point new event logging functionality at two points but otherwise the definition is still a bit murky for me. Glad to see this kind of definition!

I just added a section to the Discovery process page[1] documenting the guidelines that the Portal team uses for story point estimation. I would like to include a corresponding section for the Analysis team. It can be entirely different, since story point values never cross team boundaries.
