0 Notch or 1?
1 used to mean no notch unless they changed that.
Try to get all targets under the center of the coil with short quick side to side swipes, any of them, for the most solid and stable signals.
The better you get the more usefully information you will have.
Soil types make a difference, in great soil I could usually get most good targets pretty stable with a small range of jumping numbers from 2 directions.
On many I could get that jump down to no more than 3 numbers on the F2, if that, switching to the F70 the shear power made that number jump range larger, to about 5 numbers, but as I got practice I got them to calm down again with better manipulation.
Here in the south in much rougher soil that range is larger all the time, I get no solid stable numbers here, but I just learned new behavior to understand and compensate for that.
In both types of soil I noticed most trash, about 89-85%, did a lot more jumping from two directions than good targets.
A large range, 10 numbers or more with section jumping too and that confidence meter jumping up and down like a pogo stick.
Anything can happen out there and you never know what you are swinging over till you dig it...especially the deep stuff, but I just can't deal the trash I used to dig anymore so I set certain parameters, rules I dig by, and usually stick to them and have done pretty well telling most trash from treasure.
I don't worry about mistakes or what I miss, I just figure I will find it on another hunt on another day.
I got pretty good at this but it took many hours and after digging tons of trash and remembering common target behavior learning to do it my way...at first digging the most of everything is how you learn the fastest.
Practice makes perfect...or closer to that goal, anyway.
Seems like you are learning the tones and target IDs. 
How did you set up the detector? Did you ever do a reset?
