Modding Help How to increase the number of encounter dungeons spawned on a planet type?

I created a new planet type and encounter dungeons for it. In planet.biome I have:
{
"mode": "floor",
"priority": 5.0,
"variants": 2,
"distribution": "/biomes/distributions.config:randomEncounter",

"type": "microdungeon",
"microdungeons": [ "newdungeon1", "newdungeon2"]
}

I can eventually find them, but the planet seems very barren. I want to encounter these dungeons more often. Do I increase the priority more from 5? Do I increase the variants? Do I put the same dungeons after "microdungeons" more? Or am I in the wrong file?
