[Elecraft] W2 Directional Couplers

[Vic Rosenthal 4X6GP/K2VCO]

The 200W version has a low range that can measure power down to 0.1 
watt. The minimum reading on the 2000W version is 1 watt.

But, wondering if there is some accuracy/performance trade-off using a 2000 watt coupler on a 100 watt station?
