those numbers sound right. We are using the same calculator for our lifter. we are using a mini CIM with a custom gear box with a 26.7 to 1 reduction. we are getting it to lift 60in in 1.6 sec with 150lbs of force.

If you have the resources to make your own gearboxes i would do that, but your setup sounds good as long as you keep friction in your lifter to a minimum.
