Q1.) How is the rule-of-thumb or formula to derive the offset value? Initially, i used a small value of only 200. R1's loopback didnt manage to get offset and point to R5's E0/1 for the next hop. It only does after i increased the offset value to SG' answer of using 11111111
Rack1SW2#sh run | begin router eigrp
router eigrp 10
offset-list ODD in 11111111 Vlan18
offset-list EVEN in 11111111 Vlan58
network 0.0.0.0
no auto-summary
Using offset value of 200
D 150.1.1.0 [90/5276160] via 156.1.58.1, 04:28:53, Vlan18

Q2.) anyone encountered this? after i amended the values for EIGRP Hello and Hold-intervals, i dont see the new values applied.
