Bird accuracy is +/-5% of full scale (25W for your slug) or +/- 1.25 Watts,
so the above is within spec.  If you want better accuracy, consider the
LP-100A which is +/- 5% of reading.  At 12 Watts, this would be +/- 0.6
Watts or twice as good as a Bird...and probably cheaper as well considering
the cost of a comparable set of slugs.
