While the guild layer is a true competitive social PvP of sorts, the player-level mechanics are very close to Atlas Mine.
The overall picture is complex, as such Tempest will simplify most of it but leave theory-craft links for those interested.
How do players gain MAGIC emissions in harvesters?
It’s similar to Atlas mine, but due to Harvesters having a maximum cap on MAGIC (6 mn), this allows you to gain a theoretically larger share of MAGIC emissions as the pool is smaller.
Assuming the same boosts from player contribution, but a much smaller number of players to share emissions with, your natural rate of MAGIC is actually somewhat higher! This is even the case when emission % is lower vs. Atlas Mine.
Below is a good depiction that supports why you would want to have some engagement/exposure to harvesters over the Atlas mine.

Formula & Other means to join Harvesters
Effectively you can think of it as:
Harvester emissions % x player’s boost / total harvester’s player boosts (as usual, rarer boosts or mining power means better emissions).
For time-limited users (like Tempest!), consider using the BF flywheel via the Smol ecosystem, Realms, or try to join other guilds.
Theoretical Cap
You can only stack a number of NFTs for the harvester – they are additive in nature:
Total Theoretical max: 1315.6% (1000% (pls refer to below LG table) + 315.6% (20 Honey Combs)
Legion tonnage max = 1000%
20 Treasures (max limit = 315.6% = 20 Honey Combs)
Staking Legion Boosts Multipliers (capped by tonnage)
Locking your Legion NFTs with it increases your gains further, and yes, higher rarity = moar gains
Stacks additively to Legion NFTs – stacks differently vs. Time Multipliers
