I have flights to FRA that almost completely take up the Potential ~= Actual demand. Mannheim, which is completely contained in the FRA area shows this demand, while no flights are scheduled:
TPE->MHG 10k out of 13k (I think wrong)
MHG-:TPE ~0k (which seems be correct
Similar scenario, RTM is completely inside of AMS catchment area, which I am supplying fully. No flights to RTM, but the demand is:
TPE->RTM 32k out of 65k (likely wrong, too high)
RTM->TPE 18k out of 23k (I think wrong)
Also interesting that MHG->TPE seems right but similar, RTM->TPE seems wrong
Demand from TPE->MHG and TPE-RTM seems too high in both cases.
