That is true of the 70%. In my limited test of it it was something that you could use in a pinch, but a long way from ideal. Not sure about the 90% stuff, but I'd expect it to be better. I think I have might some around (I think the wife bought it). If I get around to it I'll give it a try and report back. I don't have any yellow heet on hand at the moment for a side by side comparison though.
