What is the difference between WPLS and PLS?

Could you elaborate on the key differences between Weighted Price Level Scaling (WPLS) and Price Level Scaling (PLS) in the context of cryptocurrency trading? I'm particularly interested in understanding how they affect order placement and execution. Does WPLS take into account additional factors that PLS does not? Are there any specific advantages or disadvantages to using WPLS over PLS? Additionally, how do traders typically decide which scaling method to employ in their trading strategies?
