Spectral sequences: opening the black box slowly with an example
For anyone reading this in the distant future: Sean is certainly right to mention the Bockstein spectral sequence. Often those BSSes arising from algebraic situations have differentials which are completely computable. There is a great nest of algebraic examples in MillerRavenelWilson's famous Periodic phenomena in the AdamsNovikov spectral sequence.

How nilpotent is the ring of stable homotopy groups of spheres?
At the very least, the proof of Nishida's theorem in II.2.2.9 of BrunerMayMcClureSteinberger comes with a bound, dependent upon the torsion order of the element x, and there are in turn bounds on the amount of torsion that can appear in a particular degree. May says that Nishida's original proof gives better bounds, and maybe more is known besides those initial things, but definitely bounds are known.
