With 8 high-end GPUs, we see a Blowfish speed of about 100 kilohashes per second. [0]
We assume we're cracking bcrypt strength 10, so we divide this number by 64 (2^10 ÷ hashcat's 2^4), and get about 1500 bcrypt checks-per-second.
There are about 170,000 words in the OED, and we choose 4 at random to give us 170_000^4 = 8.3521 * 10^20.
We can divide by 1500, but that still seems like a lot of seconds. (like, 3.5 ages of the sun)
