That's just an assumption without data. You just received data from two people on this forum, who stated they will do everything to avoid present tense prose.
My data is millions of books on Amazon. Especially those that sell. That's usable data, data superior to the personal preferences of two people. Two people aren't statistically relevant.
As it happens, I don't read stories in the present tense either. I hate it. But I read a lot of books, so present tense blurbs
obviously work. And, until I started studying how to write blurbs, I never even noticed that all the blurbs of all my favorite books were in present tense...
I didn't notice that first person stories mostly had blurbs in present tense third person either.
If someone wants to write a past tense blurb, let them have at it. I hope it works for them. I'm all for breaking rules, as long as the person understands the pros and cons (which is why people have pointed out in this thread that industry standard is present tense and why that's the case).
I've seen bestsellers where the blurb was in first person and the story in third. That
person knows how to write cracker blurbs though, so it didn't cause problems. I don't advise a beginner to try that. Nor have I seen a single recognized authority (trad or indie) ever
advise other than present tense.
