Router HSRP Active/Standby question

Question

Hello,
Can I use following command to setup HSRP Active/Standby mode for both router ?
Router A:
ip address 10.10.228.202 255.255.255.248
standby 3 ip 10.10.228.201
standby 3 preempt
Router B:
ip address 10.10.228.203 255.255.255.248
standby 3 ip 10.10.228.201
standby 3 preempt
standby 3 track 1 decrement 10
standby 3 track 2 decrement 10
Thanks

Wilson,
we don't know what objects you're tracking, so it's a little bit difficult to answer the question.
You use the default priorities on both routers (100), so, as long as track objects 1 and 2 are up, Router B will be the active router, because it has the higher IP address.
If track object 1 or 2 goes down, Router B's priority will be reduced to 90 (or 80 if both are down at the same time),  so Router A will become active, because preemption is enabled.
If the track object(s) change to up, Router B will take over again, because it also has preemtion enabled.
Correction:
Preemption only comes into play when the local priority is higher than the priority of the current active router. In your examle, the priorities on RA and RB have the same values. The IP addresses serve as a tie breaker only in the initial phase, the preemption feature doesn't consider the IP addresses later on.
Consequence: Router A continues beeing the active router.
