Nevermind I found the answer.

"Nearly every Splinterlands asset will be eligible to earn SPS tokens in the airdrop. Each type of asset will be assigned a specific amount of "airdrop points" that it is worth. Then the total number of airdrop points will be added up across all assets in all accounts in the game and held externally once each day and ~1,100,000 SPS tokens (400M / 365 days) will be divided by the total number of airdrop points to determine how many SPS tokens each airdrop point is worth that day."

So I get 1 point per DEC and every other point I accumulate is added to give me a daily point score. This then forms a percentage of all points on the platform and I get that percent share of the daily 400M tokens in that days air drop.
Sweet!

I can't wait for that first drop...
