For calculation of MLSPA pack staking rewards:

According to the whitepaper of Genesis League Sports, it mentions the following at the Reward Pools Section (https://whitepaper-goals.genesisleaguesports.com/reward-pools):

During the presale, 15M GLX tokens will be rewarded to players who stake their MLSPA packs in the game. The 15M GLX tokens will be split equally between the two presale periods. 7.5M GLX tokens will be rewarded to early adopters of presale 1 and 7.5M GLX tokens will be rewarded to purchasers of presale 1 and 2. These rewards will be distributed daily based on the number of packs purchased. For example, if someone purchases 1,000 packs and 100,000 have been purchased so far, 1% of GLX rewards going to that purchaser.

As of now, the number of MLSPA pack sold is 282,921. There are 49 days of airdrop counting from 14 December 2022.

Assuming all the packs purchased are staked, the calculation should be (7500000/282921)/49 = 0.54 GLX per pack per day.

So if not everyone had staked their packs for airdrop, the rewards should be higher than 0.54 GLX. But still not sure if you do not stake your pack, whether your share of reward will be shared by those who staked?
