Don't just stop, lift and plunge where the tab meets the part profile. Create a small lead on and off the part profile. Also, this lead on and off should actually be drawn with a small radius, rather than a simple 90 degree square corner. The radius should be a little larger than the tool radius so the the tool can actually move along the radius as it leaves the part profile.
First you get good, then you get fast. Then grouchiness sets in.
