SupplyUncle rate and the supply limit
The block rewards are exact. The uncle rewards on top of them depend on the network, which is why the final supply is a range.

Questions and answers
What is an uncle block?
A valid block that was found at almost the same time as another one and did not become part of the main chain. A later block may reference up to two of them, and both miners are paid a small reward for it.
Why is the maximum supply a range?
The block rewards are fixed by the block number, but the uncle rewards depend on how many uncles miners actually include. ECIP-1017 gives 198.5 million ETC for an uncle rate of 5.4 % and 210.7 million ETC if every block included two uncles for ever.
How much is an uncle worth?
From era 2 on, the miner who includes an uncle gets 1/32 of the block reward per uncle, and the uncle's miner gets 1/32 of the block reward. Both fall by 20 % with every era.
Is the exact supply shown here?
No. Adding up every uncle reward since 2015 needs a full scan of the chain, which this site does not have. It shows the part that follows exactly from the block height (genesis allocation plus block rewards) and says that uncle rewards come on top.
