Average break-in period for MP5/K HK/clones/copies/variants

I'm curious what others experience is in regards to what your break-in period was for any/all of your MP5/K variants/clones/copies.

My MKE Z-5RS was about 300-400 rounds probably before I stopped seeing occasional jams.

I was reading about someone with a SP5K having jamming issues with a new gun and I couldn't find any discussion about average break-in period, so I thought I would start a thread.

Reply with the make/model of your gun, and now many rounds you ran through it before you stopped seeing occasional jams. No rumors please, only reply if you have direct personal experience with a brand new gun.

I'd say for my Z-5RS, it was about 300 rounds before things started to get smooth and flawless.
