You set A to 1.1 but shouldn't the number range from 0 to 1 ? What does 1.1 mean here?

nope. the range is -10.0 to 10.0. You can also amplify the weight of a specific block.

Amplifying the weight of the entire LoRA can significantly degrade quality, but you can mitigate this side effect by amplifying only specific blocks.

The populated_vector is literally the final calculation result of the LoRA block weight spec. Variables like A and B are substituted with their set values. Additionally, you can sparsely assign block weights in the form of named specs.
