First class? About a girl-year or two I'd guess. Fully usable? About half that.

What’s a “girl-year”?

[jsjohnst]

A less male gender focused way of saying a “man-year”, a common term to imply the amount of effort, rather than an exact duration.

If someone says it’ll take 3 person-years (just to make it gender agnostic), that means if only one person was working, it’d take about 3 years. It implies that theoretically 3 people could do it in one year, 6 people in 6 months.

It’s not a definitive statement, especially if one has read mythical man month and buys into it, but gives a very tough scoping.

Presumably the amount of work that a girl can do in one year. Similar to the "man-hour/month/year" unit.
