OK guys, I have another question about AC

Is it safe to SS a score of 5 in Slushie Slinger with a time of 7-12 seconds?

A score of 5 is obtained by giving 1 customer its corresponding slushie. So basically what it would be is me giving 1 customer a slushie and then ending the game for 5 points. The reason why I want to know this is because it counts as a play so it gives a bout 6 points every 10 seconds which is really fast.

Thx for answers and will rep whenever possible!!
