CoS on EX MDF and IDFs

Experts, I am including configuration from one of our switches and would like to get opinion the configuration is fine. 

version 12.3R12.4;
groups {
ezqos-voip {
class-of-service {
classifiers {
dscp ezqos-dscp-classifier {
import default;
forwarding-class ezqos-voice-fc {
loss-priority low code-points 101110;
}
forwarding-class ezqos-control-fc {
loss-priority low code-points [ 110000 011000 011010 111000 ];
}
forwarding-class ezqos-video-fc {
loss-priority low code-points 100010;
}
}
}
forwarding-classes {
class ezqos-best-effort queue-num 0;
class ezqos-video-fc queue-num 4;
class ezqos-voice-fc queue-num 7;
class ezqos-control-fc queue-num 5;
}
scheduler-maps {
ezqos-voip-sched-maps {
forwarding-class ezqos-voice-fc scheduler ezqos-voice-scheduler;
forwarding-class ezqos-control-fc scheduler ezqos-control-scheduler;
forwarding-class ezqos-video-fc scheduler ezqos-video-scheduler;
forwarding-class ezqos-best-effort scheduler ezqos-data-scheduler;
}
}
schedulers {
ezqos-voice-scheduler {
buffer-size percent 20;
priority strict-high;
}
ezqos-control-scheduler {
buffer-size percent 10;
priority strict-high;
}
ezqos-video-scheduler {
transmit-rate percent 70;
buffer-size percent 20;
priority low;
}
ezqos-data-scheduler {
transmit-rate percent 30;
buffer-size percent 50;
priority low;
}
}
}
}
}
apply-groups ezqos-voip;

class-of-service {
interfaces {
ge-* {
scheduler-map ezqos-voip-sched-maps;
unit * {
classifiers {
dscp ezqos-dscp-classifier;
}
}
}
}
}

family ethernet-switching {
filter classify-voip {
term classify-all {
then {
accept;
forwarding-class ezqos-voice-fc;
loss-priority low;
}
}
}
}

Before I had:

class ezqos-voice-fc queue-num 5;
class ezqos-control-fc queue-num 7;

But I was told this configuration:

class ezqos-voice-fc queue-num 7;
class ezqos-control-fc queue-num 5;  is correct. Thank You
