How is hashrate calculated when all you know is luck/shares/difficulty?

Hashrate = difficulty x time
Hashrate is a measurement of the total combined computational power that is being used to mine and process transactions on a Proof-of-Work blockchain, such as Bitcoin and Ethereum

1000 hashes/second = 1 kh/s 
1000 kh/s = 1 Mh/s 
1000 Mh/s = 1 Gh/s 
1000 Gh/s = 1 Th/s 
1000 Th/s = 1 Ph/s

The hash rate of your GPU tells you how many hashes per second it can calculate. If your GPU has a higher hash rate than the difficulty, you’ll find that you have more time to solve each block. If you want to make more money from mining, you want to have a high hash rate.

Hashrate = difficulty x time Huh

This is a confused concept, what is diffculty?

Hashrate is just how many time of hashing can you device calculate (or process or do) on a block header which is a 80 bytes data (or message) during one second time period. In bitcoin, two pass sha256 calculation on a block header data consists of a hashing which produce a hash value for an message.

On CPU miners, it is very simple, how many time can hash function complete calculation on a block header data.
On ASIC miners, it is complex a bit, 1st sha256 is calculated by CPU, then, 2nd hashing (2nd pass sha256) is ran by ASIC chip. Then, output nonce is varified by CPU again. So, there are various formats to calculate hashrate in various softwares, which, I said, are not acuracy or confused.

So, I prefer how many block headers (or local works) can be processed during one second as a benchmark to quant the processing capacity of a hashing device, which can be a good base for comparation of various miner capacity. My cgminer can display how many works has been hashed out on screen.

I found that frequency increase => hashrate increase, sometime, hashed_out works can be varied or not incresed, which means device fail to increase its hashing calculation capacity. And frequency increase often produce more hot and easy to burn out asic chip. So, I only use 300 MHz for BM1397 stick.

Buying more hardware will increase your hashing capacity. But, it will cost your capital and running cost. Now, bitcoin price drops to $21k USD. Then, mage miners, pools will run under loss, and quit their business. If bitcoin drops to $5k USD, very posssible scenario, running cost will kill a lot of miners.
