...the bottom line....
1) NFHS needs to change rule regarding chip timing to be the same as NCAA, USATF and IAAF..that is, final placing and verification is done on torso.
This ends the issues of lost chips and close finishes that could change team scoring.
2) chip timing should be used as a tool.
it eliminates the human error of messy chutes and stringers with pull tags --which quite frankly you are giving the most important job (keeping those pull tags in order) to a meet day volunteer. I have never gone thru a season where at least one hasn't been dropped and they all go blowing in the wind.
3) chip timing is safer. i have seen many instances where athletes have taken headers into chute posts and /or almost been decapitated with ropes when chute changes have taken place.
An open chute is not only safer but less stressfull on all.
If an athlete collapses at the mat, meet workers just drag them away..
4) chip timing enahances spectator experience [if the right timing company is involved]. with the ability to send data such as athlete splits and team split scoring to scoreboards, announcers, internet and text messaging.
5) if there is technology available to make it easier, safer, greener and more enjoyable for all why not use it? Especially if NFHS can adjust their rule accordingly it will make it that much better.
Finally, chips on the bib are getting closer BUT still not as accurate as an FAT verification and may never be in our life time. Therefore having NFHS adjust their chip rule to coincide with NCAA/USATF/IAAF makes more sense.
ALSO, disposable chips cost more. An additional couple of thousand dollars for a meet director (in addition to the normal service fee) is alot of money.
