# A handover should mostly favor the best target rxlev:
# Two candidates for congestion resolution both reduce the RXLEV for the MS,
# candidate A results in 10 RXLEV loss, candidate B only in 5 RXLEV loss.
# But candidate A still results in a better RXLEV at the target than candidate B.
# So tolerate more RXLEV reduction if the resulting RXLEV still remains better.
