I assumed windy, tropical tidbits, weatherbell, etc. got all their data from the same models in terms of GFS and EURO, but why is the pressure reading lower on tropical tidbits?

I view windy more than I do tropical tidbits but have become accustomed to subtracting 10 to 20 millibars from whatever windy shows in the model forecast. When Laura came through I assumed tropical tidbits had the pressure too low for whatever reason but turns out windy had it too high. Thanks

Screenshots comparison from both. 12z 10/7/2020

Euro Model 12z 10/7/2020 Windy is predicting 966 mbar, Tropical Tidbits show 954
GFS Model 12z 10/7/2020 Windy is predicting 988 mbar, Tropical Tidbits show 964

Thanks

@Gkikas-LGPZ Yes, I've tried with the picker tool, and although it gives lower readings at times, (which made me consider it being a workaround), on the 18z it shows equal pressure to the reading displayed in the lines. A pressure of upper 960's is nowhere to be found. Thanks
