Power level



Power level, also known as Splatfest Power, League Power or X Power, is a feature introduced in Version in Splatoon that replaced the vibe meter during Splatfests.

The concept of power level has also been extended in Splatoon 2 to apply to Ranked Battles and League Battles.

"One of our interns has learned that starting with this Splatfest, you may notice some small improvements and differences!

During Splatfest, what was previously the Vibe Meter will now display your Splatfest Power. Your initial Splatfest Power level depends upon your current Ranked Battle rank, and your Splatfest Power level will change depending on wins or losses during Splatfest Battles.

The player with the highest Splatfest Power on the winning team will receive a slightly larger boost to their Splatfest Power than their teammates after the match.

Also – until now, Splatfest matchmaking favored grouping players with similar play styles. Players will now be more likely to play with those of similar Splatfest Power level. The higher a team’s average Splatfest Power level, the more Splatfest Points they will earn after winning."

Description
Power level will change depending on wins or losses during battles. In Splatoon 2, The power rating was changed to Glicko-2 rating system. Splats, getting splatted, turf coverage and playing the objective do not count towards the power rating. The opponents' power ratings are put together as a single value and used when calculating a new value for the player. In addition to rank and power, players also have a rating deviation (RD) number for each mode. The RD measures the accuracy of a player's rating, with one RD being equal to one standard deviation. For example, a player with a rating of 1500 and an RD of 50 has a real strength between 1400 and 1600 (two standard deviations from 1500) with 95% confidence. Twice the RD is added and subtracted from their rating to calculate this range. After a game, the amount the rating changes depends on the RD: the change is smaller when the player's RD is low (since their rating is already considered accurate), and also when their opponent's RD is high (since the opponent's true rating is not well known, so little information is being gained). The RD itself decreases after playing a game, but it will increase slowly over time of inactivity.

Splatfest Power
In Version of, a feature was added to Splatfests that replaced the vibe meter with a Splatfest Power level meter. The initial Splatfest Power level depended on player's current Ranked Battle rank.

In Version, the initial Splatfest power of players who were in Rank S+ was changed from 1600 to 1700, and the initial Splatfest power of players below Level 10 was changed from 800 to 1000.


 * Notes

The initial Splatfest Power is 1600, with 250 RD and 0.6 volatility and has seven calculation matches.


 * Splatfest Power level changed depending on wins or losses during Splatfest Battles.
 * The player with the highest Splatfest Power in a team gained a slightly bigger amount of points.
 * Players were previously matched up based on playstyle but were later matched up with players with similar Splatfest Power.
 * More Splatfest Power was gained after a match if the opposing team had the higher average Splatfest Power.
 * In Splatoon, at the top-left corner of the box showing the player's Splatfest Power was a pair of eyes representing the Squid Sister they have sided with: players on Callie's team saw scowling eyes and those on Marie's team saw more laid-back eyes. Both versions had their signature pupils, but with a dark red color instead of the usual gold.
 * In Splatoon 2, since Version, Splatfest Power was no longer displayed in Normal mode, only in Pro mode. However, the game still kept track of it internally, even in Normal mode, to determine how much a team gets for a winning bonus.

Players with the highest Splatfest Power were featured in the Splatfest Top 100 rankings.

The winners were announced in Splatoon at the official Japanese Splatoon website for Japan, Live from Squid Research Lab for North America and SplatoonUK for Europe/Oceania. In Splatoon 2, the winners are announced in SplatNet 2.

League Power
Players get their initial League Power based on their performance in their first seven matches. Every change of rotation resets the League Power. Only the League Power of the enemy team can be seen before battles.

Groups whose League Power is high enough receive commemorative medals, either Gold Medals,  Silver Medals , or  Bronze Medals and the top 100 of the rotation are displayed in previous records.

Ranked Battles and X Power


The player has a power level for each Ranked mode, although it is never exposed to the player until they reach Rank X. The game has a list of target power levels - one for each rank. If the player's power exceeds one of these thresholds when they rank up, the game will skip them to that rank.

In Splatoon 2 at Version, Rank X was added, which is higher than S+. This rank replaced S+10 to S+50. The rank bar was replaced with an "X Power" level that is exposed to the player.


 * Ten calculation matches are used for the Glicko2 initial power calculation.
 * The starting X Power (during the calculation period) is between 2000 and 2300. The initial RD is 250.
 * If the player ends up below 2000 power at the end of the month, they rank down to S+9.
 * If the player ends up below 1750 power during the month, they rank down to S+9.

Trivia

 * The promotional images for Splatfest Power show the Cats vs. Dogs and Rice vs. Bread s and ink colors despite it having not existed when they were used.
