Are DISC WEIGHTS correct?

Salut/Bonjour!

I decided to take a look at the weights of my Innova discs awhile back and was quite surprised to see that they are often incorrect. I know that not all brands stamp the exact weight, but I did a video to demonstrate this. For some this may already be common knowledge, as it has been discussed in previous forums (see below).

Inb4 someone mentions DaveD's rant about Rocs losing weight over time so he doesn't care about marking overweight discs at 180g...

 

[jmdaire27]

Really will matter how discs are weighed. And different scales will have variability between them.

Thinking about it, would it be most accurate to actually melt the plastic down to a better shape and weight that? Hypothetical. Shrugs.

About 5 years ago I scaled every Innova disc that we got in the shop for 3 months.

Stats:
940 Discs

117 were +/- 0.0 - 0.5g -- 12.4%
204 were +/- 0.6g-1.0g -- 21.7%
315 were +/- 1.1g -1.5g -- 33.5%
182 were +/- 1.6g - 2.0g -- 19.4%
122 were +/- more than 2.0g -- 13.0%

Curious now. Pulling 20 current Innova discs off the shelf:

4 are +/- 0.0 - 0.5g -- 20%
5 are +/- 0.6g-1.0g -- 25%
5 are +/- 1.1g -1.5g -- 25%
5 are +/- 1.6g - 2.0g -- 25%
1 is +/- more than 2.0g -- 5%

Not to say my scale is accurate, I don't have any calibration weights to double check it. But yea, Innova has had wrong weights for as long as I can remember. I have seen it more on the "max weight" discs. I don't think they weigh those at all. Set the machine and call it 175 or 180 no matter what. Just like the recent run of max weight Destroyers. They obviously didn't weigh them and then recalled them when the majority of them were above 178g.

I check my scales with a nickel, they weigh 5 grams.

Nice, didn't even think of doing that LOL. Well my scale is 5.0 with 1, 10.0 with 2, and 14.9 with 3 lol.

Discraft had of the 6 spare Impact discs I bought one was heavy from the 170-172 gram set was at 173.5 grams and then a 172-174 gram set was at 171.5 grams.

It is not just Innova but Discraft has it too though not as bad as they use a set of weight the disc is supposed to be between.

I feel the Innova discs get more mistakes as they have not just Discraft/DGA beating Innova due to a set of weight the disc is between unlike Innova. It seems other brands not Discraft have better manufacturing then Innova simply due to less volume of discs even with brands that are made by Innova have less mistakes in manufacturing due to less volume of discs. Part of this is how the Innova discs are made too, not using humidity control in the drying/curing process at least from what I have heard on YouTube from Dave D is that he just lets them sit in a temperature controlled room not taking into account the humidity unlike Discraft/DGA brands and now others.

Nice, thanks for keeping that data & sharing. Seems acceptable to me, but maybe to a pro that's a significant factor?

Here is a shameless plug for Marshall Street Disc Golf in Leicester, MASS...and one
of the main reasons I use them for purchases....

Weights stamped inside any given disc are rarely correct: to counter this problem
Marshall Street does the following,

ALL of their discs are individually numbered,
with a picture of that exact disc, on a scale, with the weight of the disc clearly displayed.

.....you get exactly the disc you pick out, not some
random selection from a box of whatever mold you are buying....

I am simply not good enough for this to make much of a difference. For me I group discs into three weight classes. Around 170 is medium, over 175 is heavy and under 165 is light. I generally throw light drivers, I am old. My putters are 170 and mids are generally heavy, with some exceptions.

I agree with this. Been over this a lot on here, a few times rather heartily. There isn't a person in the world that can distinguish that gram or 3 difference. There are sooooooo many other variables that affect how a disc will fly. Weight is important, sure, but nobody notices a few grams.

curious

did you weigh each nickel separately?

one may have been worn a little..? It says online that nickels since 1965 are all 5gm

 

[ohtobediscing]

Drivers 162-167, mids and putters 175.

None of my discs have ever been exactly the written weight, but atmospheric pressure, temp, and elevation differences in location could account for that. And my discs always get lighter over time from dings taking off minute bits of plastic.

I feel a focus on just a gram or two is unnecessary. My bestie worked at a mt. bike shop in the '90s where they kept a scale handy for the weight-obssessed. He got so aggravated at a lunatic one day that he told him "Look, why don't you go sell a kidney to the organ bank? They'll give you 10K, you'll lose 1 1/2 pounds, and you can afford to buy the best mt. bike ever!"

Weighed separately one is 4.9 grams. It is definitely well used, which would explain it.

What's crazy is a TON of customers that come in are very specific with the weights they want. Many many times customers have not made a purchase because I didn't have a specific driver in 171g. I had many 170g and 172g. It's craziness. I ask them a lot of questions about how they throw, how far on a specific hole, etc.

Basically it comes down to:
"I need a 171 Destroyer for this 350ft hole"
"When you throw that hole, where abouts do you usually land?"
"Near that bush on the left side"
"Hmmm, that bush is 280ft, 1 or 2 grams will have no effect on that shot whatsoever, try a Valkyrie"
"Yes it will, I really need that Destroyer for that hole"
"Okay, sorry I didn't have a 171g for ya"

Haha yep. I had this argument with a guy on here awhile ago. A new disc came out, and he was upset because it was a disc he really wanted to try, but wouldn't because he couldn't get "his weight" several retailers had tons of them plus or minus 2 grams. But he "can't" throw those weights.

Some people......

I'm not that anal but I do like my driver's around 170g. I've got them from 168g to 176g in my bag right now. Matter of fact, I bombed(for me) my 176g color glow Wraith FH about 350 yesterday evening with a 20mph crosswind.

Your scale appears to be sitting on an irregular cloth surface. Could that compromise repeatability?

 

[nothinbuttree]

I guess these are the folks that NEVER hit a tree. Or even a branch. One good tree I suspect will affect future throws more than a 1g weight difference ever would. Even on high quality molds.

Trust me, I know.
