Not clear from that post, sorry.
Is your "one operation" the EC calculation of the public key for one private key or EC points addition?
It looks like you just overestimate your calculation power adding the operations that are not really performed.
I will give a final explanation of how this works.***************************************
Imagine a house with 5 rooms. Each room has 200 people. All people have different non-repeating names.
Your task is to find David. You can go around every room, go up to every person and ask his name David or not.
In this way, you will find David by tomorrow's best.
Or you can do otherwise. Shout the whole name David to the whole room; if David responds, then he is found; if not, then go to another room.
For example, you spent 1 second on the first, second, third and fourth rooms and there was no David anywhere.
You go to the fifth room, shout out a name and get a response from David. in 1 second
A total of 5 seconds of time was spent. 1 second per room. there were a total of 1000 people.
V=1000/5=200person/s***************************************
