Not REALY .
Just too much marketing in the part of job restarts. that is all.
It is just not simple and there are to many factors involved. If they do something it can be like this. Send you fake job a couple of times knowing how long it takes for a miner to return a winning nonce at particular dificulty. Then send it again and again and measure the results. So imagine there are network issues and delays beyound pool and you as a miner and they get numbers with big variation. What will they do take avarage or what? Let us make things simple they get constant number x which equals to your delay for that particular job without any network issues during test. Then what follows next?
They decide that your miner is ok and can take restarts every second. They can not know how does your miner pic implementation handles real world mining and job restarts. How are internal buffers implemented and so on. And if they know it so what?
They will send you a milsecond job restart to Mine each and every coin on world
The most important for any pool is to send you job restart on time. Let me talk about doge. From my experience doge job restarts due to new blocks happenned at about 20-40 seconds. Let us imagine that X pool sends you job restart about 3-5 seconds late not more. Because poor doged connectivity, no external hooks bad pool software network issues or whatever. I am not referring this particular pool. I have not tested and I do not know if they send you restart on time or not. It is very easy to test and you can do it also. So you are loosing about 10% of your potential income just because of that?
Then what the f...ck does it mater how long will it take for your miner to cope with job restart. Any decent miner can take job restart quite fast.
Of course the truth is that real world job restart is a random number. But if it is constant it is beter to mine on long bloks compared to short ones
