Why Do People Sell "Heavy" Lorcana Booster Packs? Why You Should Avoid Them

I noticed people selling "heavy" single Lorcana Booster Packs. From my understanding, searching for Enchanted cards is possible since they are heavier than normal foil cards. So why would people be selling "heavy" packs. I purchased 24 packs to find out...

so the blister codes are all the same but the codes in the packs differ? interesting

So if you want to weigh for enchanted your looking at 30+ on the scales . If they weighing in at 34 it’s almost guaranteed it’s an enchanted . Current rates if enchanted is around 1 in 96 packs or 1 per case .

i know its a late reply, but how do you figure a 24.34 is a garrenteed enchanted when he pulled the enchanted from a 24.42, which weighed less than the double super rare pack at 24.44.
Basically what this shows is that the only real weighing you can do is by comparing the individual manufacture codes weights. (the ######MPG# on the back of the booster packs) In the video he gets 12 packs with the code of 102623MPG1 11 of them weighing in between 24.2 and 24.3 with one pack weighing in at 24.42. Which is drastically different than the other packs in its same manufacture batch.
--------------I basically start to ramble after this point.....---------------------------------
Weighing lorcana packs is pointless for the average person. It only comes into play if you're intending to resell. Where you buy a bulk of packs, weigh them comparing them to other packs within their same manufacture batch and keep only heavy outliers.
Note that each booster pack "sleeve" (the cardboard around the outside of a booster pack) will have the same code on it.
these codes for the first chapter set are likely:
Date + MPG + (machine/assembly line code)
Notice that the Booster pack sleeves do NOT have a number after the MPG but the Booster packs do.
What happens is each booster pack is made on an assembly line / machine. they get stamped with the date of manufacture + MPG (it seems its always MPG so that has some internal meaning i dont know what is) + stamped with a number representing which machine line they came from.
then after the sealed booster packs are made. they get sorted into which product they are going to be in: Deck box, Lumineer's Trove, Blister packs...etc.
You may notice that every pack in a Lumineer's Trove will have the same Code on them. But Packs in a On the shelf blister pack display won't always have the same code. and deck boxes only have 1 pack anyways.
then when they are put in their product's packaging that product receives a code as well. All Blister packs in the same display will have the same code on them. as they were packaged at the same time. but the booster packs within the packaging may not.
With this knowledge you can (very unlikely) buy two blister packs from the same display but receive 2 enchanted rares within them. As the booster packs themselves do not always come from the same batch. However, you should never receive two enchanted rares from a single lumineer's trove as all of its packs should come from the same batch.
Basically all the packs are made at the same time. and are seeded. Recently me and my girlfriend were opening up two lumineer's troves from ursula's return and we were going one by one on the cards. for our commons we noticed something interesting. I pulled a card and her very next card would be the same card. then i'd reveal my next card and her next common would be the same. As in: I revealed card A. She'd reveal her next common and it would be the same common as me. Then i revealed card B and her next common would be the same one. this went on for 4 commons in a row. Her pack would have a different first common than me but her second common would be the same as my first common, her third the same as my second, her forth the same as my third, and her fifth the same as my forth her 6th common would be different than my fifth though.
and we only noticed this on commons. All of our packs had the same Code on the back. even though we had two different lumineer's troves. My theory is that every Code on the back has 2 enchanted rares within them. and that for each individual code on the back there are 200 packs per Code. with each code being divided up among Blisters, Decks, booster boxes and Troves.
An additional fun story. my only Enchanted rare that i pulled came from a Manufacture error trove. I recorded my opening of it, where i was shorted 8 rares. My most of my packs contained: 1 foil, 1 rare, 4 uncommons, and 6 commons. where you should receive 1 foil, 2 rares, 3 uncommons, and 6 commons. Originally i thought i had a resealed trove. but when i pulled the enchanted rare from it. I knew it wasn't resealed because why would you reseal it and not take the enchanted rare.
In addition your enchanted rare will always take the place of the foil. Meaning if you pull an enchanted rare it should always be the last card and you should receive 2 rares or above in addition to it. With the exception being manufacturing errors.
