Please do not get upset!
Many aspects of the certification of aircraft are based on stalling speeds and it makes sense (that is gives increased safety) to use the highest possible stalling speed for any given weight and flap configuration. This will be always be the one associated with idle power and with the CG at the forward limit.
Manuals would be unnecessarily big and complex if they included stall data for all CG positions and power settings. But that does not mean that thrust levels do not affect stall speed by carrying some of the aircraft weight, it just means we do not take such matters into account when calculating stall speeds for various purposes as such effects will always be on the ‘safe’ side.
