A while back I swear I was having the same issues as the OP in terms of the SRM acting funny when sometimes up shifting into 5th gear from 4th. I now understand it was driver error as I was hitting the gate of 4th very slightly on my way to 5th.

However, for a period of about 2 weeks I was trying to replicate the issue by up shifting from 4th - 5th between 4-5k rpm continuously all the time, during my commute, during my spirited driving, etc. I must have done a few hundred of these upshifts in that RPM range. However, I was very careful about these upshifts and never shifted hard or too fast. I would go up from 4th, pushed the shifter to the right and up into 5th - I never once diagonally up shifted and always kind of eased it into 5th during these up shifts.

It remains smooth as butter but I can't help but ponder if that did any damage to the synchro but continuously up shifting or if I accelerated any kind of wear. Again, it shifts great for the record.
