Since I've had it so long (SX @ 24 - DX @ 35 - now 71), I was trying to guide myself along the chart to see how I progressed.

For the first 11 years I was prob. a 1.5
After DX and the next 16 yrs prob. a 2.5/3
After 2nd DX-the next 9 yrs prob. a 4.5/5
From age 60 to now 11 yrs prob. a 6 to a 7.

NOT going any higher..
