A couple questions about reusing yeast and amounts to use

[earwig]

I am going to reuse some yeast for the first time this weekend. I used Mr Malty and it says for a 1.049 OG I would need 886ml of wash slurry, just under a liter, this seems accurate/fine. My question is for this same OG it says I would need 2.1 packs of dry yeast or 6 vials of liquid yeast with a start and 17.2 without a starter... how could this be accurate? Am I using the calculator wrong somehow?

Thanks for any info you can provide!

Did you enter it in as 1.49?

You sure you didn't put in 1.49 instead of 1.049?

6 vials in a starter and a liter of slurry is just as ridiculous as 17 packs.

Defiantly put it in as 1.049.

When did you harvest the yeast?

at 1.049 i get:

2 packs dry
88ml slurry (towards the thin end) havested a week ago
2 packs w/o starter
1 pack w starter

Duh! Thanks guys. I didn't pay attention to the harvest date and the default was set to October of last year.
