Personally, this has much to do with the individual's priorities pertaining to WikiTree's method of reward system as it pertains to real work in genealogy. While I think most people use the honor system pretty well, some do not. You can spend an hour a day really involved in a difficult profile and gain a few contributions. Example would be a working on a single profile and adding one census record after another and saving each time. Then going to the bio and over-saving each minute (even though WT saves a draft). So, no I do not think that contributions necessarily equal hours spent. To summarize, I think most everyone has good intentions, but we should exercise good judgement with what is regarded as progress.
