[Mldxcc] Question about 40M inverted V dipoles

So at W1RH Bob's suggestion I decided to get my butt in gear and built a
40M dipole. It's an inverted V so it fits on my lot with a center mast
currently 27 feet up at the center - 10 feet up at the ends. It has a
1:1 balun that I had for a while from LG.
I tuned it to 7.1 MHz the logic being:
7.1 = 14.2 (x2) = 21.3(x3) = 28.4(x4)
So I used my antenna analyzer and trimmed it up to 1.1 to 1 at 7.1 and
it dips to 1.2 at 21.6 (odd). The antenna analyzer doesn't show any dip
at 14.xxx or 28.xxx. This I don't understand.
However I get a perfect 1:1 match on the rig with it's tuner all across
all of those bands which I guess is somewhat expected. It also tunes
flat at 17m and 12m.
Does this sound right/safe?
