Convergence values

I am currently conducting a study on Solidworks using FEA to analyse the bending stress of a valve disc assembly, throughout the majority of my simulations most components i am getting results that are converging nicely with the use of a H-Adaptive method, however the results i am now starting to get are not converging as well as I hoped they would. For example, my latest study bring back the following von misses stress values in the following order:

Iteration 1 - 74.96 N/mm²

Iteration 2 - 84.55 N/mm²

Iteration 3 - 118.5 N/mm²

Iteration 4 - 140.4 N/mm²

Iteration 5 - 175.1 N/mm²

Would I be correct in saying that the iteration 2 is the best result as after this point the values jump up quite fiercely in comparison to the first two studies.

Any advise would be greatly appriciated,

Thank you
