The discrepancy is visible
The selected TREK Biscoff3×50g source highlights9g plant protein. Its nutrition table shows9.8g protein per50g and20g per100g. These are the three actual presentations in the record. This site does not decide that the headline is a typo,round one field to overwrite another or invent a reformulation date without maker evidence.
Do not repair it with arithmetic
Multiplying20g by0.5 gives10g,but that does not make10g the observed per-bar table value. Label columns can be rounded and a website can combine versions;the source alone does not establish which explanation applies here. Keep9g,9.8g and20g in their respective fields rather than presenting a corrected value as if it came from the current wrapper.
When the issue matters
If an exact nutrient figure is central to the purchase,ask the maker about the selected Biscoff3×50g version and check the actual received pack. If the purchase question is simply how many declared bars a retail pack contains,the three-bar count can still support stock arithmetic. An unresolved nutrition field need not block unrelated,clearly supported pack-count information.
A fair comparison example
A buyer can compare ordinary food-mass rates across the three selected offers while explicitly withholding an exact price-per-protein ranking. That gives a useful shopping result without pretending the source conflict has disappeared. It also avoids using a lower headline for one product and a higher table value for another simply to favour a chosen option.
Keep the evidence with the order
Save the product ID,declared3×50g contents,the dated source values and any maker reply. If the parcel is a3×40g version or another flavour,do not assume the reply applies. This is a source-verification step,not a personal intake calculation or proof of nutritional performance. Independent food/nutrition/content review remains pending.
