Well if venting the dryer indoors, how much would it raise the indoor
relative humidity? Only from 40% to 60%? I should think it would be more
than that...

Based on what? The depends on the number of loads of laundry...

1 load.

wetness of hte laundry,

12 pounds of water.

size of hte house, etc.

A 2400 ft^2 average US house with 0.7 ACH, dried in H hours,
with a 0.0025 outdoor humidity ratio.
