I am convinced anything over at least 80% is completely wrong. Definitly. The only heat exchangers that achieve over 95% are the huge industrial type that cost more than your house. If there are results over 100% then they are quite obviously wrong. In this forum we obey the laws of thermodynamics. The other flow could be Cmin.

Car heat exchangers are in the 40% range. A paper i was reading expressed worries about using a heat exchanger of over 60% as it is "too good" because you end up paying more money for it.
