I read PB.effectiveness and the EFF_SOFT comment path described from data.js on 29 Oct 2026. Older guides still print a 0.5 to 1.5 clamp and a 3-second regen. Both are out of date. Regen delay in the current rules file is 2 seconds.

What a raw table cell becomes in a match

Raw cell	Meaning in the file	Factor you should expect
1.3	Super effective	1.2
0.75	Resist	0.85
0.5	The old “immune” cell. It is not a true zero.	0.7
Two cells multiplied	Dual-type defender	Product, then clamp to 0.65–1.35

How the counter finder works

Look at both of the defender’s types. Multiply the two softened factors.
If the product is above 1.35, the fight uses 1.35. If it is below 0.65, the fight uses 0.65.
A type that used to “do nothing” still deals 0.7. Do not draft as if an immunity exists.
Type counts on the roster page tell you how many families share a type. They are not a counter list.

Questions

Did the type chart change?

Yes. From version 2.0 the public effectiveness function softens the raw 1.3 / 0.75 / 0.5 table to 1.2 / 0.85 / 0.7, then clamps a dual-type product between 0.65 and 1.35.

Can I find counters for a dual-type Pokémon?

Yes. Choose the two defender types above. The reverse list ranks incoming attack types by their computed factor; expand the chart for all 324 single-type pairs.
