Reduced from 5 to 3 miles for A320 behind 777 at Paris. Almost cut in half.

"Thanks to Recat EU, the distance between a 777 and an A320 has dropped to 3 nm from 5. A controller may also want to introduce a bit more space between two aircraft and insert a third one in between. In any case, the level of safety is unchanged."

Cat B followed by Cat D in RECAT EU is 4nm, not 3.

Correct.
"The separation minima are determined specific to each Aircraft Pair. For example, at the moment, an A330 following a B777 (Heavy behind heavy) requires 4 miles in trail. With the new rules, that is reduced to 3nm. An A320 can now follow 4 miles behind a B777, instead of the current 5nm."

Level of safety unchanged, oh sure. So, if you expect a wake encounter under current rules and you can expect a wake encounter in the new rules, it is unchanged?
