Actually the arguments of the extra queries is not a valid one, it's like saying can't create more than 10 threads a day, because there will be more queries !!!

nonsense, adding 5 more reps, is actually in the same query (looked at the source code), the result is 5 more rows, not 5 more queries, the query is the same !!! and in terms of CPU utilization 5 rows or 10 rows when the database is localhost (same server) doesn't add any CPU time, not even 1ms delayed reponse time !!!

so the answer is no slow down, or CPU hog for going to 10 reps or even 20 reps,

check the source code, it's all there

so what's your excuses this time DD ?
