How so? Thanks.

It sounded as if the seeing wasn't very good and that it was coming and going quite a bit. It is difficult to get good comparison results when the seeing isn't very good and is changing rapidly.
Maybe that particular Stowaway had a problem but the results of the review don't fit my experience. I've looked through several TV-85s they are very nice, but I also know that my f/7 Stowaway gives outstanding views.
My scopes are not safe queens they get out under the night sky. Here are some of the small refractors I currently own.
Celestron SS55F f/8 fluorite doublet TV-76 ED doublet Takahashi FS-78 fluorite doublet Unbranded 90mm f/5.5 ED doublet AP Stowaway 92mm f/5 fluorite triplet AP Stowaway 92mm f/7 ED triplet

Your statement and the Bill one are right. But, IMHO, that only demonstrates the fact that the TV85 is so good that to compare it to very high-end triplets, larger in aperture, even must be made in carefully controlled conditions. It is easy to forget that the TV85 is only a doublet…
Botton line...
The TV85 rules! 
Sorry, I am a pathetic fundamentalist.
Yet you speak the truth. When I got my NP-101 and compared it with the 85, I soon discovered the smaller scope matched up pretty well. Yes, it does show some CA when a bright star is highly magnified, but for the most part, I don't see any CA to speak of. None with the moon. Mostly it's dimmer than the 101. It still resolves images with the best of them.
