Re: more replications or more runs?

That's a good point, but I guess if it does not have any effect on the design of experiment I could consider it later when I will be working on analysis of the results.

Re: more replications or more runs?

Although it is the same number of runs if you look closely at the attached file it does have an effect on the design since the algorithm gives a different set of runs. You sacrifice some power on the main effects to be able to possibly model the interactions. You are banking on the effect sparsity principle and by utilizing a stepwise regression you are hoping to "tease" out a more complex model.
