It's so easy to get bogged down by the minutia within this hobby, especially newcomer/amateur/average members.
There is a wealth of examples of models on this forum, made by folk who know and always will know far more than you will ever get the opportunity learn.
I don't think my suggestion here will be very popular in certain circles. However, here goes....
Study these models made by what I may term 'academics' of the subject. Rigging, for example, has dimensions that were empirically developed over hundreds of years. The 'academic' modeller has the resources and invested time in its study and application.
By studying 'academic' models including their rigging intelligently it's possible to get a sense of what's right, and by your own efforts find out what looks wrong. Generally, it's all about proportion; the relative thickness of one piece of cordage to another.
My opinion (for the little it may be worth) is for all practical use, most ships could be rigged by however many bits of 'sting' get the job to look right to the average modeller.
Then you will have learned to value the respect of others examples.
And the time you have borrowed from them will allow you to fix that shelf or get that slow puncture repaired properly and safely.
