Sometimes it takes a little bit of time for the plays to register, maybe 5 or 7 seconds after chosen. What I do is double check that the plays I chose registered. I try to make as many plays as possible but I realize that the system takes a lot of capper's plays simultaneously, so sometimes I am guilty of rushing while the wheels are spinning. I haven't found it taking over a minute as of recent and overall it has been pretty effective.
Not sure it hasn't seemed slow to me? Took less than a minute to put in my 9 or so nba plays...maybe a more tech-savvy person can jump in with an idea...
