I think its ok signal mostly drop when you stop after a speedy sprint but one thing must be kept in mind this app only gives correct readings with at least 6 SATs Locked mostly it tries to lock 12 SATs below 6 SATS it will give you wrong speed and app back light will turn into yellow from gree and if another SAT is dropped or goes out of range it will turn red and the SPEED appearing on it will be completely imaginary
..
when ansee's bike sprinted I think it had last instance of two locked SATs as shown when it lost the last signal when he stopped after sprint or may be Ansee can tall better himself
but in any case CG125 has a speed of 106 in factory specs and if tuned to well 110 is very easily achievable, even it can go beyond if road conditions favor like non feelable down hill as its rawalpindi and all city is on uneven terrain....
