Whoops.  Extra parenthesis was actually referring to the line below
this one, AKA:

> +                       mas->oversampling = 2;

...that still applies.  ...but then ignore my comment suggesting that
you base your series atop Stephen's.  You already did that.  Certainly
you should mention somewhere in your email that your patch is based on
his.
