I have 4 PCs and two of them now show this odd behaviour. To illustrate better following is the customised menu I am using for per peer Bandwidth Outgoing Limit

</menu>
<menusep/>
<menu label="Outgoing Limit">
   <menuradioitem label="No Limit" setvars={outlimit=0}/>
   <menuradioitem label="/s" setvars={outlimit=2000000}/>
   <menuradioitem label="/s" setvars={outlimit=1750000}/>
   <menuradioitem label="/s" setvars={outlimit=1500000}/>
   <menuradioitem label="/s" setvars={outlimit=1250000}/>
   <menuradioitem label="/s" setvars={outlimit=1000000}/>
   <menuradioitem label="/s"  setvars={outlimit=750000}/>
   <menuradioitem label="/s"  setvars={outlimit=500000}/>
   <menuradioitem label="/s"  setvars={outlimit=400000}/>
   <menuradioitem label="/s"  setvars={outlimit=300000}/>
   <menuradioitem label="/s"  setvars={outlimit=200000}/>
   <menuradioitem label="/s"  setvars={outlimit=150000}/>
   <menuradioitem label="/s"  setvars={outlimit=100000}/>
   <menuradioitem label="/s"   setvars={outlimit=75000}/>
   <menuradioitem label="/s"   setvars={outlimit=50000}/>
   <menuradioitem label="/s"   setvars={outlimit=40000}/>
   <menuradioitem label="/s"   setvars={outlimit=30000}/>
   <menuradioitem label="/s"   setvars={outlimit=25000}/>
   <menuradioitem label="/s"   setvars={outlimit=15000}/>
   <menuradioitem label="/s"   setvars={outlimit=10000}/>
   <menuradioitem label="/s"    setvars={outlimit=5000}/>
   <menuradioitem label="/s"    setvars={outlimit=1000}/>

Now what always used to happen was I would select one of these speeds and it would appear in the right click menu of a selected peer and then in the main menu, in the Priority column (This is not an output formatting issue I think so lets put it aside for the time being). Now what is happening is that instead of the right click menu containing the set speeds above (first column) these new scaled? speeds are available (second column).

KB/S KB/S

1250 1220
1000  976
750  732
500  488

So they are all being scaled by 97.6%, what is causing this on some computers and not others?

Welcome to the KB vs KiB confusion! Initially a kilobyte was supposed to be 1024 bytes. But drive manufacturers wanted to cheap out and considered a kilobyte to be 1000 bytes.

F1 for this menu (note the numbers are in BYTES): https://support.tixati.com/bandwidth%20customize%20menu

Tixati has a setting in https://support.tixati.com/settings%20-%20user%20interface%20-%20output%20formatting  for this. You have two choices:

1. Use the "ki" prefix (binary, 1024) everywhere and enter power-of-two numbers in the configuration you pasted. Then the number will be round
2. Use the "k" prefix (decimal, 1000s) then the round numbers you entered will match up.

It still holds that you should limit total bandwidth to about 85-95% of the actual total your ISP provides you. That number will be in kilobits (1/8th of a kibibyte... 1024 bytes/8) or megabits (1/8th of mebibyte... 1024 KiB/8). Again, the depiction is purely visual.

Yet there's a bug in bandwidth limiter: https://forum.tixati.com/support/5246  / https://forum.tixati.com/support/7098
