Default Another myRef version

Sorry for my bad english..
This is another version of myRef. Just tested with stock op-amp in my school lab: LF353, TL072 and LM358.

is this a MyRef or is it a composite opamp configuration?

I can't see the Howland current pump in there.
I can see some similarities to the Jung topologies, but there seems to be some errors in implementation.

I'd also say "MyRef" amps should follow the scheme of a (howland or not) current pump in the loop of an outer opamp.

In this sense, this amp wouldn't be a member but it could be a workable composite amp. While the power stage itself looks stable with the noise gain applied, the whole amp might have stability problems?

Should I report the Thread and request that the title be changed to something that does not misuse the term MyRef? even though it is written as "myRef".

Or will the Member do the honourable act and remove the MyRef from the title
