Honeywell rewrite policy vs. Default

[techservices]

N4 help. Doc not much help
On a Honeywell Stryker VAV wire sheet
Network input points under AX property sheet , have a rewrite policy Vs. default drop down
Menu option
Was told should select” Rewrite policy” over “default “ or else these point values will fall into
Infinity.Guy Zebrick posted this in Best practices, which I was not able to find.

Do I Understand correctly . I will Duplicate a Tuning policy ,name it "ReWrite Policy", Give it a One minute rewrite time,and Select it for Non Network Setpoints.
I am curious though as to what points are safe to use this Tuning policy. Points that only write when there is a change of State?

I use it on Network input, such as occupancy or mode(cooling heating auto). I don't use rewrite policy on all the network input, just the important ones. Don't use it on network setpoints, that would cause your Jace to crash.
