The bounded generic-base-gap conjecture for finite Morley rank actions

From papers

Let (G,S)(G,S) be a definably primitive permutation group of finite Morley rank. Let b(G,S)b(G,S) be the minimal cardinality of a base, and let b1(G,S)b^1(G,S) be the least positive integer nn such that SnS^n contains a generic subset all of whose tuples are bases. Bounded generic-base-gap conjecture. There is a natural number dd such that

b1(G,S)b(G,S)<d.b^1(G,S)-b(G,S)<d.

This proposed amendment allows the generic base size to exceed the minimal base size, as happens in many algebraic examples, while conjecturing that the gap is uniformly bounded. The source gives no resolution of this formulation.
