Yeah mate its bugger all now and with using RDC helps as well.
Not sure why you would use a powershell script when repadmin does the same thing, anyway sites and services should eb the place you want to set replications times. I set mine to 15 minutes but depending on dns transferes you might want to make it more but i have bugger all users thatn eed to know an ip in another location.
If you are not sure, use repadmin comamnds to check the latecny or failed attempts.
This shows all replication using the More comamnd as the screen scrolls a lot depending on DFS name spaces.
repadmin /showrepl * | more
This one will show you the time differance and shows updates.
repadmin /replsum *
