Well I'm posting here something very interesting I've found about some DT maps with different pp efficiency levels, and how some kind of pattenrs are pp ineficient and how some others are too pp efficent. Here I post you my toughts of 6 different cases of DT maps that can give 250's pp. Starting from least pp efficent to most pp efficent.
07th Expansion - worldenddominator [La cataline]: Old school map that is really tricky at terms of tapping complexity and with some really unfortable patterns and known for having a duplets spam that bothers most persons. You can still enter to its #50's even playing no mod.
Skillet - Hero [Insane]: Another old school map that is known for being a challenge to many due to the really uncomfortable spacing and slider shapes.
Lindsey Stirling - Elements [Fire]: This is a respectful map that isn't too farmed due it has some interesting streams, sliderstreams and some curius jumps. It's not friendly or badass for pp means.
Skrillex & The Doors - Breakn' a Sweat (Original Mix) [Insane]: This map is really fine, but it is being a way too abused due it drops absurd pp values on really high accuracy. The higher your accuracy is on here the more overrated in pp your rank on this is.
Primastella - Koigokoro [Deli's Insane]: Koigokoro isn't an easy map, but is known from being one of most farmed maps in osu. From being overrated on this star system and high amount of circles this map proves it's very pp friendly aswell its sister the Insane is.
Tsunamaru - Daidai Genome: This map is indeed the most broken pp map in existance. Nothing easy but at being too overvalued it encourages too many players to farm it. OVERRATED at both star system and from pp given by accuracy.
Facts to considerWorldenddominator 213 bpm, OD9, AR9.67, 5.41 stars, 485 circles, 291 sliders
Skillet hero 213 bpm, OD9.67, AR9.67, 5.39 STARS, 418 circles, 208 sliders
Lindsey Stirling elements 210 bpm, OD9, AR9.67, 5.73 stars, 392 circles, 206 sliders
Breakn Sweat “210 bpm”, OD9.67, AR9.67, 5.31 stars, 332 circles, 320 sliders
Koigokoro 210 bpm, OD9, AR9.67, “5.51” stars, 348 circles, 125 sliders
Daidai genome 203 bpm, OD9.67, AR9.67, “6 stars”, 425 circles, 70 sliders
Conclusion1.- Troll patterns with higher amount of sliders are being underrated, regardless if they're OD9.67 because there is no accuracy from sliders.
2.- PP optained from accuracy at higher values of OD + higher amount of tapable elements is very farmable.
3.- Maps with comfortable spacing and easy tapping but high settings and high spacing are the most farmable.
4.- Most pp efficent maps end being these with higher relation of circles/sliders, more circles more accuracy, if more sliders... well I'm not sure...
Most pp efficent maps are both overrated from star system and their settings, this needs fixing later.
