A real world example: nobody likes spam mail, cold calls and other forms of aggressive marketing.
50/3000 = 0.0166 or 1.66%
10/3000 = 0.0033 or 0.33%
2/3000 = 0.00066 or 0.066%
or if we compare players that remained to how many were interested at first
2/50 = 0.04 or 4%
From devblog:
4.09% is also a hard number. That’s the percentage of new players that have stuck around in EVE after 30 days during Q1 of 2019.
Your noble attempt yielded (way) lower results than the average at worst and on par at best. Maybe your way of doing things is not as “new player friendly” as you think it is? And yet you want/propose to funnel (force) new players to something they might not enjoy.
New eve players are fine in NPC corps - there are plenty of like-minded players with similar experience to talk to. And Help chat is already a good tool to answer whatever questions they might have, although i think a little bit more strict moderation is required.
