That's how much Crumb Cake I've wound up with (786m). Out of eight ounces (.23kg) of wool, which means, what, 1720 yards (1573m) per pound (.45kg). Which isn't totally extreme lace spinning (a Shetland lace spinner could probably get that yardage per pound out of one ounce of good wool), but it's as extreme as I ever hope to get.
I'm going back to sock-weight three ply. With some orange pencil roving I bought at the yarn store on Monday.
Though it would be kind of cool to ply one single of orange variegated with one single of carbon fiber. It'd look like burning charcoal. Maybe. Hm.
