Hello, I'm using 2 RX 580 GPUs
When I use -clKernel 0
The hash rate moves up & down, most of time it is showing 64 MH/s, sometimes go down to 58 MH/s
The average 5 min. is just above 58 MH/s
When I use -clKernel 1
The hash rate is more stable, most of the time is 60 MH/s sometimes go down to 59.7 or so
The average 5 min. is about 59.8
With kernel 0, looking at it, the average appears to be over 62 MH/s
What I must believe the 5min. average or what I see on the screen?
Could the average 5 min. with kernel 0 be wrong?
& why just after starting miner it tell me the 5 min. average when I have been only mining for 1 min. or even less?
Thank you.

Over time the higher the average the more shares you find. You can also use "-dcri" to optimise your hashing rate. In PH 3.0 this will be automatically tuned for best param like in the Claymore - a promised feature of the PH developer. For now do it manually. It might increase your hash even further and bring more stable hash rate on default kernel.
High hash rate fluctuation (several MH/s) is an indication of overclocked setup. The card is attempting to compute at the maximum speed but at times it throttles down due to the increased temperature or other factors internally managed by the GPU bios. There are quite few things you can do to address this. Rig cooling - add external fans, reduce core/mem clocks, manage ambient and rig (gpu) temperature ...
When you start the miner the average is calculated with the available data. In the first few minutes that is less than 5 minutes of data regardless of the listed "(5 min)".
