nzarkos,
I'm sorry to have to welcome you, here. I am glad, however, that you've found us. There is a lot of good information and even better people within these walls.
Progression is a difficult thing to measure. My wife, Darcey, was told that she was within 6 months of life's end in March of 2016. That prediction was based upon the progression that her neurologist had been following. Darcey is still with us and will, I believe, finish out 2018. So progression, which varies from person to person, can also vary for each individual person... in that it can speed up and slow back down.
Our lessons were to take advantage of all that you can do today. As progression begins to make certain tasks or functions difficult, find new ways to do them or find other things to do. There is still a lot of life left after diagnosis, once one gets past the shock. Elect to live each day well (in spite of ALS) if you can.
My best...
Jim
