Default ev2mk4

I am planning to buy ev2mk4 from my friend.
On crony he get there speed results.
Speed is in meter/seconds.

1.223,4 m/s
2.230,4 m/s
3.230,7 m/s
4.230,5 m/s
5.234,6 m/s
6.232,1 m/s
7.232,4 m/s
8.231,4 m/s
9.233,3 m/s
10.229,7 m/s
11.233,1 m/s
12.233,3 m/s
13.232,3 m/s
14.232,2 m/s
15.233,1 m/s

Are those ok readings?
I am worried about this first shoot of 223 m/s.

Fire one shot off then another 5 over chrono leaving 15 second intervals and then let it stand for 2 minutes and then chrono another couple of shots.
And if that first one is low, then you have a problem with the reg ( leaking/reg creep )
Hope this helps.

As Dave said, a low first shot is often because the reg pressure has crept up since the it was last fired. If shots at 15 second intervals have very similar velocity to shots at 15 minute intervals then the reg is ok, if the 15 minute interval shots are lower then the reg is creeping too much and needs repairing.
