I think we (that includes jgt) have understood that. The problem is: verifing the DB creates a certain amount of usage on your disk subsystem because it causes (quite some amount of) disk I/O. if you run several instances of it in parallel it depends on the amount of disk I/O a single instance creates if these several instances run faster linearly with the number of instances.
i.e. if a single instance of the script taxes the disk 10% then running 5 simultaneous instances will drive that up to 50% and run perhaps somewhere in the ballpark of 1/5 of the time. If a single instance taxes the disk already 100% then running 5 instances in parallel will perhaps run about as fast a single instance because you can't tax any resource more than 100%. The disk I/O will be queued (thus serialised again) and this will put a cap at runtime. Perhaps reality is somewhere in between those extremes but you may want to find out beforehand where you stand.
I hope this helps.

NAME
script - make record of a terminal session
SYNOPSIS
script [-a] [filename]
DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
record is saved in the file typescript. See WARNINGS.
The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
when the forked shell exits or when Control-d is typed.
OPTIONS
The following option is supported:
-a Appends the session record to filename, rather than overwriting it.
NOTES
script places everything that appears on the screen in filename, including prompts.
