xxdeathx's point is valid though. stacked red/green lines literally don't matter. Here's an explanation from what I know, a lot of this is just paraphrasing from talking with other QAT's
How red/green lines work is, osu will always prioritize green over red lines. try it with any map. change the red line to soft, and add a green line with Normal sampleset. Osu will make the section Normal and not soft. You can see this with SV changes. Osu will always take the green line value so if theres an SV change between red/green, the section will never be 1.00x SV. Green > Red
The problem is when theres two stacked red lines or two stacked green lines.
Two stacked green lines with different sampleset = osu doesn't known which value to choose so it may take from both, or combine values:
Example, Green Line 1 = 20% volume, sampleset Soft,
Green Line 2 = 50% volume, sampleset Normal,
You may get an output like = 50% volume, sampleset soft. which takes values from both green lines. It's the same idea with red lines. Green line is 1st priority, and red line is 2nd priority. If they are stacked, osu will always take the green line value over the red line value.
Green = Green > Red = Red
I'd like some context as to why this is considered unrankable besides the fact that you heard someone say so. I trust information that i've tested to be true over 2nd hand information xP.
