It's been sitting in th fridge for a few weeks from the last brew. I took it out of the fridge hours before to let it warm up. Then I dumped it into the bucket.
Yes this was essentially the problem I was having with my 1g scale. I would pour and the weight wouldn't change. Then I wondered what the heck was going on so I would scoop the powder out and just dump it all in and it's like 5g more than before. Haha
I just realized I might done something stupid. When I dumped the pint of yeast cake into the wort, I left some of it floating. Should I have stirred it in? I'm wondering if it is worth opening the fermentation bucket lid again.
