In deed this might be the simplest solution in doing this now why didnt i 
think of this in the first place :)

new - old / 6 = value (negative or positive)
where value is what is needed to add every 10mins if real interwal is 
that should work right then making the heartbeat 10mins instead of 60mins
higher datarate whould make it look better but then again it whould 
increase database size alot!
