One week will not be enough. One week per inch is a decent guideline. I would rather cure for two weeks, equilize, and soak to desalinate, then risk undercuring. As long as you followed the MTQ recommended ratios, you cannot overcure. Oversalt, yes.
Going by palpation to determine whether a belly is cured/equilized, is a poor indicator. Each belly differs in muscle and fat distribution.
