comment FindInstance only satisfies half of my double inequality
My way of thinking with "heuristic" functions such as FindInstance[] goes like this: if it comes up with something, wonderful! If it doesn't, it just means I have more legwork to do.

comment Multiply integrand with -1, and the precision changes?
Yes, I wouldn't expect "ExtrapolatingOscillatory" to work without preliminary symbolic processing, how else can the zeroes where the integrand will be split at be determined?

comment FindInstance only satisfies half of my double inequality
What if you split the inequality into two with &&? Also, why not use the exact values, like Log2[999999999]?
