litecoin – How is mud calculated

Hello I used to be making an attempt to know extra about mud in Litecoin and what’s thought-about mud. I stumbled upon https://theliteschool.com/lsc/staging-core-releases-and-litecoin-dust , however I do not perceive some issues:

1. What’s “smallest common output measurement”? Common of what? The transaction outputs? So what’s “smallest”? If we did a mean there is just one end result…
2. Similar for “smallest common enter measurement”.
3. Mud adjustments from block to dam? From transaction to transaction?

Additionally, this can be a few years outdated now. Is that calculation nonetheless right? Is it the identical for Bitcoin?

Thanks
