Ideal Stream patterns

[Patashu]

When you ask 'what pattern do I make this stream?' The first question to ask is 'given the bpm and how abrasive I want the file/this part to be, how hard do I want it?'

Hard spread patterns are things that (from easiest to hardest):
-Are not evenly balanced over 3-4 fingers (the less evenly the harder, if it's perfectly even you just jumptrill it)
-Tend to have minitrill patterns in them, the more often the harder (for pad it's the opposite), minitrills that link only one column at a time count too e.g. 12324232123234323132323432 (notice the long run of alternate 2s and then 3s)
-Tend to have one handed minitrill patterns in them, something like 12123432123434 or 12321232123232123 is really hard spread especially if it has 24ths/32nds in it that also follow the one-handed minitrillishness of it instead of being your typical hits-all-four-columns burst

These also apply to jumpstream patterning, just look at any icyworld file and you'll see 99% of his js is set out to be easy to hit (even over the columns, tends to keep trills on opposite hands, etc)
So if you want to make hard stream just do the opposite

also, the reason why index patterns minus dumb trill stuff are highly comfortable is because it restricts you to a subset of all possible streams, meaning the stream hitter has to decode less information per note, it also tends to hit middle fingers more often than the outside fingers but I'm not sure if that's related or not
