We do the payments with batches of 1,000, and then repeat the ETH addresses in these batches.
For example, this week you received 3 times 1,000 FUDD, which are 3,000 in total. In this tx: https://etherscan.io/tx/0x082139f5c6c78ec1778a692c9dd8f58a098795d2ddaf84e456ef567a96e9912a
your address (0x477...) is repeated 3 times, so you had 3,000 FUDD
