Default Mr Malty Vs Beersmith 2.0 Yeast Starter

I am planning on brewing tomorrow and need to make a starter for an 11 gal batch. I am trying to figure out how big of a starter I need and getting two totally different answer from Mr Malty and BS 2.0.

Wyeast 3711 Produced 1\30\12 for 11 Gallon Batch

Mr Malty Says:
458 Billion Need
2 Packs of Yeast
2.5L Starter

Beersmith 2.0 Says
417 Billion Needed
1 pack of Yeast
1.1L Starter

Not sure what I should be following here. Any advice?

Haven't tried bs 2.0 yeast feature yet. Does bs ask for yeast date? What is the OG? Also what method are you keeping suspension?

1.1L starter seems pretty small for an 11 gal batch. I usually use a 1L starter for a 5 gal batch.
Whats your OG?

Yes, BS 2.0 asks for the yeast date
1.060 is the OG
Stir Plate

I went back to make sure I have everything the same in both places. Maybe I am just slow.

Here is a screen shot of the BS 2.0. The beer is the "How Rye Am I Saison" from HBT

weirdboy - I just went back and checked Mr Malty and it says 83% viability. Obviously that is the difference, but why such a big discrepancy???

That is based on the production date. Either your smack pack doesn't say 1/30/2012 on it, or the date you put into in Mr Malty is wrong.


EDIT:

OK, I just tried it in my copy of Beersmith 2, and it shows a viability of 88% with that package date on Wyeast. So something is messed up in your calculation there...maybe you need to update to the latest version? There have been a plethora of bugs found & fixed...

Smack packs both say 1/30/12 and date is correct in both. I have version 2.057 and it says it is the latest when I check it. It is Wyeast 3711

All of this aside would you do a 2L starter with 1 or 2 packs of yeast?
