Where is thet recipe/instructions from?

If it's your first mash I'd let it go 60 minutes just to be sure.
Unless you have a time restraint.
Are you testing for conversion?

I also don't understand the 3.5 gallon boil.
For a 5 gallon batch you should be collecting around 6 - 6.5 gallon of wort to boil to around 5.5 gallon.
