दौड़ती है हिमालय तट से सागर, हमसफ़र हर राह पर, हवाई जहाज़ों को त्याग कर, करो अक्सर, भारतीय रेल में सफर. - Arpit P

today tracked from Etw to Maitha, 108 kms in 52 mins... for one or two stations it might be little mistake but for longer durations you will get the clear value.. for example if you will see a train crossing 8 kms in 4 mins, then it might be the work of seconds too which will mean that it will be near to 110, but for a longer period if the same gap continues then the MPS will be above

yes sir , main point is Long time observtion.
for 1 or 2 stn like 4-5 min NTES may give error value but doing it long time like 40-50 min will give correct analysis ..
