JE:-
The logic speaks for itself:
You made the accusation so
you must provide at least
one example, or retract it.
Ok?

JE:-
No, I have supplied an experiment but you
have only supplied a modelling simulation,
(as I have previously taken great pains to 
point out).

JE:-
I am happy to follow this modelling 
simulation. IMHO the outcome is
predictable.

JE:-
It is not an experiment it is a
modelling simulation.

Relative fitness within Hamilton's
rule is defined as _any_ comparison
between rb and c. Do you agree or
disagree?

JE:-
Take it one step at a time.
Step one:
Altruism within Hamilton's rule is 
defined as any positive c. Do you
agree or disagree?

JE:-
Here is the rule with the absolute
fitness of the actor _explicitly_ 
included within it:

		rb>K

Only this ONE case proves altruism via 
the rule re: the _absolute_ fitness of 
the actor. Do you agree or disagree?

If you agree:
What is the net result for the actor 
re: its own fecundity?

If you disagree:
Please provide your version of the rule
with the total fitness of the actor
_explicitly_ included within it.

JE:-
Exactly. You admit non exist
by simple default of your failure 
to define any.

JE:-
My question was about as subtle as
a sledge hammer smashing a brick ;-)

I insist you answer this question.

JE:
I cannot believe what you
are claiming here: you do not
know what a simple deduction 
is.

If you claim that 4+4 = 8
then you must also claim
that 5+7 = 12, right?
You cannot validly claim that 
4+4 = 8 but 5+7 does not = 12.
Either both are correct or 
neither are. Ok?
This is because both are 
only simple deductions from
exactly same inductive set of
mathematical definitions
that allowed both additions
where just one invalid deduction
refutes ALL these definitions.

Any rule that does not refer
either directly or indirectly
to a minimal/maximal/constant
value must behave in the 
same way: contradict itself.
Hamilton's rule is NOT an exception.
This is why Dr O'Hara had no other 
choice but to reluctantly admit that
no difference between "a reduced positive 
c and a negative c" exists anywhere within 
Hamilton's rule. Nobody here understands
that this _proves_ the rule is logically 
_invalid_ so the rule stands refuted
within any _science_. ANY rule that cannot  
measure the difference between such 
a _basic_ difference can only make 
self contradictory measurements. 
This is the case re: Hamilton's rule
where a cost c that makes an absolute
gain cannot be differentiated from
a cost c that makes an absolute loss!
However, even such an absurd rule can 
remain _mathematically_ valid.
