Well, to respond on your points, I'm rerunning the first arc for a new group, so I've started to look at the encounters more but have not examined the BI's too much yet. You did identify the first-run BIs, which I've been at and definitely drew out Fate Points at times - if this was done to draw out Fate Points, I understand the intent/desire during those events. I'll agree that Fate Points were high/pooled too much, and the awarding of Fate Points seemed to vary greatly judge to judge.
Just wanted to post a gentle reminder going forward on this resource being limited now. Overall, the earlier BI I played via home play seemed fine, from what I remember - the first runs, which I've only been to two, seemed to draw/require their expenditure much more.
I definitely like the Fate mechanic, and prefer it be used and earn on a even footing, but requiring to spend and change Fate all the time is the only concern I wanted to address.
