What a nonsense...

Tape drag not a huge effect, but can add up to 10 or 15 points over the
course of a contest. That's why many top Euopean contest pilots use a
special putty compound to smooth over the tape edges. It's a bit
tedious for a single day's flying, but if you're going to stay
assembled for a week it's not so bad.
