Predicted FG - Big change from Mobile 2.2 Full to 2.3

I just got a new Kindle (Fire HD 8 - 6th generation). My old Kindle (Fire HD 7 - version 7.5.1) was running 2.2.48 since it wouldn't run correctly with anything more current. Everything was backed up to my Amazon Cloud account so when I activated the new Kindle, it loaded BS automatically. However, it somehow loaded version 2.3.4. This may be the issue since I don't think I have heard anything yet about 2.3 for Kindle. This may be the Android version.

So, what is happening is that 4 of my recipes are resetting their predicted FG once I open them for editing. The 4 recipes are all Belgians (2 Belgian Special, 2 BDSA). Example: A BDSA with OG 1.109 and FG 1.022 (BS 2.2) changes to FG 1.006 with BS 2.3. It only resets once I open for editing. The only recipes it does this with are the Belgians. The one thing different in them from my other recipes is that they are the only recipes that use Belgian candi sugar. It seems to think candi sugar ferments on steroids.

Is there any fix for this?

Thanks.
 
Yes,
  Sugars do ferment at a much higher rate and BeerSmith does take this into account - in fact I think the change was made in 2.2.  Before it did not take into account sugars higher fermentation, however the new numbers should be more accurate overall.

Brad,

Thanks for checking in. I thought it might be a Kindle vs Android thing. It just seemed strange that the FG changed so much. These were recipes on which I had hit the BS 2.2 predicted FG pretty closely and had attenuations in the 80s. The new numbers are also significantly lower than my actual FGs for these brews. Of course, that's not to say I haven't missed an FG or two in my day :)

These new numbers would push the attenuations into the 90s. For the example in my first message: Belgian (4 gal) with 14 lb grain bill and 2 lb candi sugar. OG 1.109. The BS 2.2 predicted FG was 1.022. Actual FG was 1.023 (79% atten). BS 2.3 predicts FG 1.006 (94% atten).

There are other brews where the new expected attenuation is in the 92-95% range. One even predicts 99% attenuation. That just seems too high. Could this be a Kindle issue or is this really accurate? I am not what I would consider an expert brewer so I will definitely defer to your experience on this.

Thanks,
Chris
