Correct information or information at all

I have started to add my Finnish banknotes to Numista and I noticed that some information is not correct. Should there be some kind of checking before adding or is it just so that some information is better than no information? At the moment I do not have enough time to correct all that but hopefully on my summer vacation I do have that time. I also have some banknote types not yet in Numista.
Some banknote sizes are not correct, some issuing years are not correct, some Krause catalog numbers are not correct or photos are not correct, just as an example of not correct information.
It is good to have banknotes to Numista, but it would be better to have correct information in first place, that is my opinion.

I also would like to know is it target to have added all different signature variations too?
