I'm sorry, it is "that much" by any reasonable standard - I'd guess it'd be in the top 20% of GGL/CCR, which would make it 140/7,000,000 people or the top 0.002% of programme members.
That said, it isn't necessarily that punishing - it's equivalent to 3 J long hauls with a connection, six LHR-HELs or 2 QR returns.
I think it depends on travel patterns but with that much flying, LT gold status on Asiana for *A would only be a year away.
