H = the order in which the neighborships were established.

 

SRTT - the time in milliseconds it takes to send a packet to that neighbor and receive a response. 

 

RTO - the time in milliseconds the router will wait before retransmitting a packet in the retransmission queue to that neighbor.

you can not interpret it "meaning can not config"

this value is calculate from router for eigrp update message and ack message return from peer.

but you can use it to detect L2/L1 issue between two eigrp peer.

 

do you want to see this value change ?
if yes 
add Sw between any two eigrp router, then wait until establish eigrp between two router, finally shut down the interface from one router to SW and check the value you will see 
0 5000 1 <- this meaning L2/L1 issue between two router and this happened because the one router link is UP and send message and other router link is down, 
the router with link UP don't receive ACK for message and the value change ""0 5000 1""
