Power ERG mode for short interval

 I use Elite Qubo Digital Smart B+  when doing very short interval during traning there is a delay of a few sec untill power build up, for 10 sec intervals somtimes Its miss 50~10% of the time and this effect the traning measure, Even I keep the power after passing the finish bow (There is also delay in reducing the power) it dosent measure. The SW can actualy know abou this just follow the cadence and see that I keep it or even push faster trying to get the power.

Appriciate if the SW can compencate for the delay for example by given a few sec time frame to get the power and then start measure the interval time.
