The component counts available for SMD/THT types in the report is independent of the variant.
I checked the reports for multiple variants, and the count is always the same, which the solderpaste calculation is for the variant for instance.
The feature request is to also provide the counts for the components in the variant only.
It would be useful to have the counts of components for the variant at hand.
As for the solderpaste calculation which for the variant for instance.
Extract from the full report template:
# General stats
Components count: (SMD/THT)
- Top: ${top_smd}/${top_tht} (${top_comp_type})
- Bottom: ${bot_smd}/${bot_tht} (${bot_comp_type})
