When participating in the 3f testnet, the number of rewards per day is about 22,000 times, while in the 3g testnet, the number of rewards per day is only 16,000 times. Is the mapping ratio of each reward from 3f and 3h to the mainnet the same?
If I understand you question correctly the answer is yes. The difference is since there is more space pledged rewards are less often in later testnets.
According to the official announcement, it is 0.1% of the total weekly amount. My understanding is that the exchange ratio should be calculated on a weekly basis. For example:
3F test gets a total of 2200007 = 1540000 rewards in one week, and the exchange ratio should be (1B0.1%)/1540000 = 0.65, that is, one block reward converted into ATC is 0.65 Token.
3G test gets a total of 1600007 = 1120000 rewards in one week, and the exchange ratio should be (1B0.1%)/1120000 = 0.89, that is, one block reward converted into ATC is 0.89 Token.
