Hi everyone,
This is just a general warning about the scoring method of Bestcommentaries.com, which up until a few months ago was my go-to source on determining which commentaries I should buy (and still is for a rough guide). Before I pass my critique though, I do acknowledge that they have stated here that "A numerical rating can never fully capture the value of a work. It is only included here as a guide to help students of the Scriptures know where to start."
With that in mind, I wish to just make a note about the scoring method. More or less, this score can be reduced to a "popularity contest" more than anything. I always wondered why I would always see some exceptional commentaries with relatively poor ratings vs. some of the more basic devotional/exposition commentaries. Why is this?
Here is the formula: score = (weighted average) + (# of times in a library / 10) + (# of overall reviews / 10).
The highest scored volume is D. A. Carson's PNTC commentary of John. Here is the part I find strange. His commentary is used as a benchmark for all other commentaries (set to 100) and then everything is scaled relative to this with a score between 60 and 100.
Since the "best" commentary is very subjective, I understand this is very difficult to then quantify. My humble two cents is that one also keeps in mind the type of commentary they are after (ie, textual/exegeitical, pastoral, devotional etc) and choose accordingly. Read the amazon reviews for the text too, as these can often provide more information on what the commentary offers (something which I applaud Bestcommentaries.com for providing access to).
Hope this is helpful.
