I'd like to give one possibility here, if it's not the tuning hammer tips. At the PA PTG convention Jack Stebbins gave the illustration of just completing a concert tuning in an auditorium when they switched the air conditioning on. There went the tuning. If in your particular case a rather drastic weather or humidity change was occurring (or air conditioners were on), and if you were using a highly accurate ETD such as RCT or SAT, could that have resulted in the tuning changes? I also use tuning tips with a somewhat loose fit, and it has not been a problem for me.
