I just did the belts on the SD. Surprisingly, with new belts, no slippage will occur even with 3/4" deflection at the center of the belts.

These two belts are very narrow and will easily stretch, so you don't want them too tight. My suggestion is to set them up so you've got about 1/2" of slack when you press in the center between the alternator and the water pump. If the belts are relatively new, they do not need a lot of tension. This will save both the belts and the water pump.

You'll know immediately if the tension is insufficient. With the headlights on, the belt will let out a squeal that can be heard down the street.
