Yeah!!!!

Thanks for correcting. Actually, the recipe above is valid, changing grms
for grs (grains), a kind of old weight unit. In grams it becomes 8 and 18
respectively, still a bit more concentrated than other recipes I've seen.
What I'm wondering now is wether I made my experiment with the mistaken data.

Maybe I'll need to restart it all over.

Cheers
