A SHORT WORD ABOUT THE DRAGY

I HAVE PROBABLY SEEN 2 DOZEN TUBERS AS THEY UNBOX A DRAGY AND THEN GO TO THEIR LOCAL DRAGSTRIP TO TEST HOW ACCURATE THE DRAGY REALLY IS. THEY WILL RUN A FEW QUARTER MILE PASSES AND THEN HOLD THE TRACK TIME SLIP UP AGAINST AND THE DRAGY PERFORMANCE REPORT SAVED ON THEIR SMART PHONE AND TELL THEIR AUDIENCE THAT IN THEIR OPINION THE DRAGY IS JUST AS ACCURATE AS THE TRACK ACCUTIME II TIMER.  THEN THE SHOW'S HOST HOLDS UP THE TRACK SLIP AT 11.2200s AND THE DRAGY APP SHOWING AN ELAPSED TIME OF 11.22s AS PROOF.  THE PROBLEM WITH THAT STATEMENT IS THAT WHAT THE TEST ACTUALLY PROVED WAS THAT THE TRACK'S TIMER IS AT A MINIMUM 20X MORE ACCURATE THAN THE DRAGY. LATEST CLAIM ON THEIR WEBSITE IS THAT THE TOP OF THE LINE "DRAGY PRO" HAS A SAMPLING RATE OF UP TO 25 HZ AND THEORETICAL PRECISION OF +/- .01s (.01 / .0005 = 20) AND PRACTICAL AGREEMENT WITH A PRO-GRADE TIMING SYSTEMS (LIKE THE ACCUTIME II WITH A KNOWN MAXIMUM TIMING TOLERANCE OF +/- .0005s) THAT IS ON THE ORDER OF +/- .03s. .03 / .0005 = 60 SO IN PRACTICAL TERMS THIS MEANS YOUR LOCAL DRAGSRTIP'S ACCUTIME II SYSTEM IS BETWEEN 20 AND 60 TIMES MORE ACCURATE THAN THE DRAGY'S GPS BASED SYSTEM.
