Mumbai Traffic Police — Wrong Traffic Fine

I am sent 3 fines for vehical MH01DE3154 for speeding. All 3 are unfair and wrong challans. They calculate speeding from speed limit of 95 whereas sign boards on the road read 100. There are hardly any boards announcing odd speed limits like 95. Also my vehical speed in all cases was exceeding by as low as 1 KMPH to max 8 KMPH which must be within tolerance limit as it is not possible to calibrate speed with this exact level of accuracy
