are coils more forgiving when there are more of them? I have had some trouble doing 4 wraps an my AGA T2s and this time I did one with 5 wraps and one with 6 and they both took little effort to get them perfect. I am an rba noob so I really don't know. This was just something I noticed. It could just be that I am getting better at building them but the last working 4 wrap coil I built took me like 6 hours and a ton of starting over with new wire to get it working properly.
