This is not due to the scale but to the fact that the portions of the XP truffles may differ in weight. That is why we mention in the enclosed A4 manual, on the product page, and in the Frequently Asked Questions section, that the weight of the portions may vary. It remains a natural product and unfortunately it is not possible for the producer to get exactly 1 gram in the portions. I have already discussed this with him and he is going to mention it on the packaging in the next printing so that it is clear to the customer.
Also, you never know exactly how much psilocybin is in 1 serving. Sits can also vary from 1mg to 2mg, so it's still a bit of intuitive microdosing, if you're working with truffles. A scale is therefore not a luxury.
Apologies for this inconvenience, Thanks for your understanding.
