Because the
totalinstance variable only updates ininitialize, it does not reflect the correct value whenadd!is called. This fixes the problem.A test case is provided to show the bug/fix.
A more robust solution would be to use a
totalmethod instead to return the calculated value. It may be worth checking if such a solution is generally faster than doing the calculation every time a Tms object is created/updated. Benchmark the benchmarking! :-)
