Data Comparing Mining Profitability and Internet Speed?

Does anybody know of any information relating to mining profitability and internet speed? Has Vosk or anybody else conducted tests relating to this? If so, what does the relationship look like? How much more profitability does faster internet translate into?

the vast majority of mining requires very little internet usage. latencey/ping has an effect on it. but from people i have tlaked to along the way as long as your ping to the mining pool is lower than 80ms it shouldnt matter much.
