My bet is no worries, it is better to run them heavy than too light for sure. Cartridges are a whole lot more resilient than we think.
Did I do any damage. . . .?
So today for some reason I checked my Dynavector 20x2L stylus force with my digital force guage. To my amazement it read almost 2.8 when it should be between 1.8 - 2.2. I clearly recall setting it to 2.2 the last time I checked it. I don't know what happened, but the real question I have is did I do damage! I've only maybe put between 20 - 30 hours - maybe less. I checked with a loop and couldn't see any obvious wear, but I'm not an expert.
