It totally depends on the MSC.
After several years on Marketforce's "do not call" list, I've recently been offered several lucrative routes. Not money like in the good old days, but I did accept 17 at roughly $100 each. It took me several days to cover them all, as they ranged from WY through NE, eastern CO, and southwest KS. IIRC, maybe a couple in TX and OK, too.
I also made my own route of 11 gas stations with IPSOS by checking the board every hour and snatching them up when they hit $90 each. Which I did on purpose and deliberately, as I had bid a route of these stations at $45 each and never heard back from them. They didn't even bother to tell me they received my route, which I spent hours on, to meet their new requirements for routes.
It also depends on the scheduler. I'm giving up on a particular scheduler with SeeLevel because her typical reply to questions is....crickets. Which can leave the shopper hanging.
Other schedulers with the same MSC will talk with me on the phone and work out a route, or answer questions timely.
And this is part of why I urge shoppers to develop a relationship with your schedulers. A good one can make your day (month, year! ), and a bad one....well, avoid when possible, and keep contact minimal when avoidance is not possible.
