If you want to make your life a little easier.... Get yourself a silver sharpie to mark the balancer at 10deg, 12deg, 14 deg, whatever your looking to advance to. Those little lines can be a pain to see. I marked mine at 10 and 12. Didn't like the way she was running at 12, moved back down to 10.
Happy now.
Markers make it a little more eye friendly, especially when you have to look through all the accessories to see the indicator and balancer.
You should have someone by your side who has done it before and do not forget to put the plug back in after you modify the base timing.
10 degrees made a noticeable difference to me. Some others on the forum go higher. Typically around 12-14.
