According to my experience TAT AM transfers are usually done in 12-48 hours.

He's talking about transferring to direct, which is actually contingent on both TAT and friedcat processing the request. Even if TAT initiates the request within 12-48 hours, one would still need to wait for friedcat to process it, and these days he only seems to be processing transfers once per week. (But typically he clears outstanding xfer requests befor processing divs.)

I'd day, it's best to not push shares on the day of divs or the day prior. (You prolly won't lose them, it just might get muddled.)
