I would have more confidence in these figures if the names of these compounds had been spelled correctly.
You might check with the original poster, as I've known posters to mistype or misspell words by accident. It doesn't affect what the poster is trying to say, except that they just did a typo. I just copied it straight from the other FReeper who put it on a thread.
I wouldn't want to second guess the situation with that other FReeper ... :-)
[ ... I could have clean up the spelling, but I hesitate to do that for other FReepers and like to leave it exactly as they typed it... although I did change the formatting slightly ... but that's a different situation than typing ...]
