Please become accustomed to provide decent context info of your problem.
It is always helpful to support a request with system info like OS and shell, related environment (variables, options), preferred tools, and adequate (representative) sample input and desired output data and the logics connecting the two, to avoid ambiguities and keep people from guessing.

Totally seconding jim mcnamara, some hints on condensing your script into one single awk script, just trying to translate your code, no reasonable testing possible:

Code:
awk -vSARR="string-1 string-2 string-3 string-4" '
BEGIN   {for (MX=n=split (SARR, TMP); n>0; n--) SRCH[TMP[n]]
        }
/^@/    {tot++
        }
        {for (s in SRCH) if (($2 ~ s) && /^@M/) count[s]++
        } 
END     {print "Total:", tot
         for (s in SRCH) print "MID" s "\t" count[s]/tot*100
        }
'  $1
