Doesn't work for me even with ‘emacs -Q’. Are you sure you are seeing
0.5 second delay?

Here is how I test it:

1. Start Emacs with ‘-Q’ flag.

2. Evaluate:

  (setq blink-matching-delay 0.5)

3. Re-check its value and description: ‘C-h v blink-matching-delay RET’.

4. Open some file with long data within parentheses, scroll down so you
   don't see opening parenthesis.

5. Delete closing parenthesis and type it manually.

6. Period of time for which opening parenthesis is shown is always 1
   second. You can set it to 5 seconds, it will be 1 second no matter
   what.
