If your asking for values, you need to be more specific. JAR 25 aircraft have performance requirements that need to be fulfilled for the various climb segments, of which the second segment is usually the more limiting. Those figures would normally be the lower end values that you might see. The Saab 2000 for example I would imagine being well above the climb requirements under any circumstances. I guess it is up to the manufacturer during design and the operator during operation to make sure that these values can be complied with, be it unfeathered or feathered. Usually the performance manual states the conditions under which the values of climb performance are valid.
