I don’t agree, because if you look at the way most clients show zap counts, they simply put the total amount of sats to the right of the ⚡️ symbol. Why is this so hard to understand?

Yes, they use the Lightning simbol because zaps are transmitred by bitcoin Lightning Netwok to send sats/bitcoin to someone.

You can zap once, many sats. Or you can zap twice 1 sat each. Zap = tip, sat is the bitcoin cent.
