Q. on OSPF cost settings on interfaces with different speeds

Hi,
 assuming I have the following topology:
 
 
 R1 -----------(SW)------------R2
    f0/0 e0/0
 
 with R1 and R2 running OSPF.
 Should I adjust the ip ospf cost on R1 to reflect R2's cost (or viceversa)?
 Having a different cost on each side of the link may cause asymmetric routing to happen (assuming a topology a little more complex than the one I drew) and I wonder if it is required in the lab to have the two interface costs matching.
 
 I believe that when a task explicitly requires to change the cost we have to do it on both side (right?), wouldn't this be a similar case?
