Hi Duke!
I would like to revisit this issue of 'MED' being seen as 'LOW', as I don't know whether you have spotted this pattern...
The 'MED being seen as 'LOW' happens predominantly in the 'Supply Level' column and very rarely in the 'Demand Level' column and I mean very rarely, maybe 1 instance out of every 5-6 Stations OCR'ed.
This is happening to me a lot too. See, for example:

Anyone got any idea why this is happening or how I can fix it? It seems really unusual - of all the OCR errors I can imagine, mistaking MED for LOW seems really unlikely.
