I beg to differ. It is not uncommon at all to find unseated strings in uprights and grands and the reasons for this situation tho subject to a lot of speculation and casual number pushing is hardly charted clearly. It goes without saying that there is a stronger tendancy for strings to pull away from a negative crown / negative bearing situation then positive/positive due to the very nature of the upwards forces involved. The impact of the initial pulse on the bridge, string leverage moments on and around the bridge, climatic factors and a probably a good deal of other factors are all part of the picture. That strings unseat from the bridge is a simple fact that is observable. Conditions that this can occur under are drafted in the article I wrote for last Junes Journal. Anyone who wishes can objectively confirm that all these can and do occur by open minded experimentation.

It would take a tremendous negative bearing to pull a string up off of a bridge against the slanted pins and offset angle, unless pin slant was only very slight. Otherwise, strings don't un-seat from bridges. Ron N
