Incorrect payout – Unclear answer [solved]

On 10/25, I posted:

our payout for a $32 product is $5, which is a .15625 multiple.
In Settings I chose Referral Rate and entered .15625. When I save, it reverts to .15, which shows less than $5 commission for our affiliates.
I also went to the product page and entered .15625. When I save, it also reverts to .15.
Please, how do we pay a $5 commission on a $32 product?

You responded:

There’s an alternative which allows amounts instead of rates available https://github.com/eggemplo/Affiliates_Custom_Method-Products_amount

looking at the code, https://github.com/eggemplo/Affiliates_Custom_Method-Products_amount/blob/master/affiliates-products-amount.php, I see

$product_rate ) == 0 )

should that be changed to $product_rate ) == 5) ?

and I don’t see where to edit product id:

if ( $product->exists() ) {
$product_id = $product->id;

here?

Also, I did a remote file search for affiliates-products-amount.php. Nothing.

Am I supposed to create this file? If so, what folder???

I got it that you are programmers and all of these questions “should be obvious”, however, there is NO WAY the average wordpress user is going to figure this out. And, isn’t one of the primary reasons we use wordpress is that it is easy?
