If your Garmin is like my Garmin, I don't think you can delete individual data points....which really stinks....b/c you can't correct obvious errors such as this.
Here's a pdf file (attached...I hope it works) with some printed screenshots from my TrainingCenter (Garmin desktop app). Note the highest elevation point (1925 ft at mile 15, which was on Tower Road). The highest % grade I registered was 16%, which - predictably - was at mile 4.6, which was at the end of Fox Tower (the "wall"). A few sections on that road ranged from 14 to 16%.
