By "99% of the Rakudo spec tests today", do you mean "99% as many spec tests as Rakudo on Parrot passes today", or has Rakudo managed to implement 99% of the specification on both the JVM and Parrot now?
For what it's worth, I'm pretty sure Rakudo JVM passes more tests today than any p6 implementation did at the start of the year. It's just not quite as capable or user-friendly as Rakudo Parrot yet.
