Hi,
I made an adjustment on the processing of the girth ; in order to be sure that the length is the highest value between the three.
In the plugin, under the line
$parcel->Girth = (($parcel->Height + $parcel->Width) * 2) + $parcel->Length;
I pasted
var_dump(array(
'l' => $parcel->Length,
'w' => $parcel->Width,
'h' => $parcel->Height,
'g' => $parcel->Girth
));
In order to have some debug data.
For my product 14.5x1.75x0.004 in ; with 4 products in the cart I got
array (size=4)
'l' => float 14.5
'w' => float 1.75
'h' => float 0.016
'g' => float 18.032
Which looks normal regarding the documentation or other instructions that we can found on the Internet.

After that I retrieve the USPS test account we got, configure it with activating all shipping services, in "parcel" mail type and "variable" container.
The plugin gave me some quotes for the 4 products in my cart and the prices looks "good" and not illogical for a shipping in the same state.
So, with the data I got from you and with the latest version of the USPS plugin (I updated once again the plugin in the previous post), I got something which looks good.
If you have still troubles with that, please provide some data which will help me to reproduce your configuration in my test website.
Regards,
