Question about prompting

what's the difference between low ((low quality, worst quality)) and (low quality, worst quality:1.2)?

((word)) = increase attention to word by a factor of 1.21. Basically difference between ((word)) and (word:1.2) is 0.1 stronger attention to a word.

Some people also use []. Each [...] is times 0.9 and each (...) is times 1.1.

I'd recommend sticking to the (low quality, worst quality:1.2) / (low quality:0.8) notation. It's far more readable and easier to finetune.
