I recently had me BS11 strung at 31lbs with BG65 on a adidas machine and after 30 mins the string ping was 1316hz . Does not it seems a little high ? Considering initial frequency to be around 1340 , it seems to me the ping relates to 32 or 33 lbs . What say ?
That is a little bit high... perhaps he had prestretch set at 20%... Anyways with BG65, it would probably drop to 1200 Hz in a week or two...
For what it's worth bg65 only drops about 10hz in the first hour for me. So if it is a good job maybe only 5hz in 30mins so could have been 1320hz fresh. Although my 32 usually is about 1270hz. Never got bg65 above 1300hz highest I have strung is 31/33. I don't use pre stretch though.
There was no pre stretch . Indian stringers do it for living . They don't have a clue about badminton in general . they just learn it as a technician.
