Sparring

[Tiny]

I couldn't find the answer to my question in any forum threads, so if this is a rerun, my apologies:

It's no secret that one of the principles of Bakbakan is routine live-round sparring, and that the success of their students relies on this a great deal.

How often do you all (indicate which system you come from, if you're so inclined) stick-/knife-spar?  Once per week? Twice per month?  Do you feel that routine sparring is one of the keys to progress?  More so than, say, stick flow drills?

many thanks in advance for your replies (hopefully there will be a few!),

In our group we live spar at least once to twice every two weeks.  Although this is with helmets on rather than fencing masks to insure we will be able to spar in the weeks to come.
