May I go on?....very amusing. If yes I try with 20017 30017 40017.
Yes, no rules now but if you pick a maker already found by others (or by yourself) you'll receive 5, not 50.
(otherwise you or others can go 6018,6019,6020 and it will be boring...now it will be useless too)
Why 5 and not 0? Because I won't make a list of all the makers already out and you can't look back to check them all, so if it happens, you won't be too penalized.
