Default Timescale convergence?!

Hi guys,

I'm running a NACA0015 profile at low reynolds numbers (10000-1000000) with steady sst including gamma-theta transition model. I varied my timescale to become a converged (steady state) solution. But I found out, that in some cases both decreasing and increasing the timescale from my converged timestep gives me an oscillating (transient) result.

My question is, does the "good" timescale maybe damp transient effects so the solution can convergate?

Cheers
