The generic GloFAS v4.0 model performance is measured by the modified Kling Gupta efficiency in Figure 2. High skill (above 0.7) is shown over much of the higher latitude areas and also some southest Asian and central south American areas. The lowest KGE, including even some catchments with no skill at all (below -0.41), are spread across some tropical areas, often in central southern USA and Mexico and some areas in Africa, often in the drier climate.

In terms of magnitude, the larger errors mean 5-10 days or even over 10 days timing problem.
