I've never done anything like this, so take what I suggest with a swimming pool of salt.
Could you just scale your SW after calculating the mean? For instance if you get a mean of 1.4, divide all the stabilized weights you have calculated by 1.4 and then rerun. The other possibility here is there may be a missing factor. Whenever I see 1.4, I immediately think of two possibilities - square root of 2 (the remainder is lost to round off) or square root of the normal variate for .975 (=1.96). If either of those is a possibility, check your sources.
