What affects your build time
As a Technic-style build, expect sub-assemblies, gears and mechanisms that slow the pace to roughly 170 pieces per hour, slower than a standard set of the same size.
Your real time depends on experience, how often you pause, and whether you sort pieces first. The SetSquad app times your build bag-by-bag so you can see exactly where the hours go, and how you compare to other builders.

How we calculate build times
We estimate build time as piece count divided by a typical adult build pace, around 300 pieces per hour for standard sets, faster for large display sets, and slower (~170/hour) for Technic. Estimates are clearly labelled and are replaced per-set with the real median build time once enough builders have logged their times in the SetSquad app.
