Setting up semantic partitions ASE

Running  ASE 15.5

We have a  non-partitioned table  with 640 million rows. We are looking at setting up range semantic partitions  by create date

There are 200 + million rows for 2013 and 380 + million rows for 2014

I am thinking about setting up following partitions by create date:

Partitions 1  -  4 :  For 2015  By quarter   

Partition 5 -  For year 2014

Partition 6   -  2013 and and earlier

Add new Partitons for each new  year  ...

Only updating  current data  --  i.e. any data more than month old is no longer updated ..

Is this a viable breakdown ?
