3)The problems was caused by the MM and using BucketMem_ASM solved it.

Running this testcode

procedure TMainForm.Button1Click(Sender: TObject);
var
I1, I2 : Cardinal;

begin
for I1 := 1 to 2 do
begin
BenchmarkButtonClick(nil);
Update;
end;
ValidateButtonClick(nil);
ReportRichEdit.Lines.Delete(ReportRichEdit.Lines.Count-1);
Update;
for I2 := 1 to 2 do
begin
BenchmarkButtonClick(nil);
Update;
end;
end;

Gave accuracy 0.4%
