Using "let" the way he uses it is not "wrong" either, since its supported in Bash, (although I do agree it's not necessary.)

The way he used it is wrong. He was using it to assign a string.

In any case, I do not recommend bad practices to people just learning the shell. One may be using bash now, but in the future may have to use a shell that doesn't support let in any context. If it added something to the script, there would be some justification for it, but it doesn't.

NAME
sysstat - sysstat configuration file. DESCRIPTION
This file is read by sa1(8) and sa2(8) shell scripts from the sysstat's set of tools. It consists of a sequence of shell variable assign- ments used to configure sysstat logging. The variables and their meanings are: HISTORY The number of days during which a daily data file or a report should be kept. Data files or reports older than this number of days will be removed by the sa2(8) shell script. COMPRESSAFTER Number of days after which daily data files are to be compressed, either by gzip or bzip2. SADC_OPTIONS Options that should be passed to sadc(8). With these options (see sadc(8) manual page), you can select some additional data which are going to be saved in daily data files. These options are used only when a new data file is created. They will be ignored with an already existing one. FILES
