 The formulas seen in the `make_metric` macro invocation are computed by the host and will thus have zero impact on the targets performance. The `set` method on the metrics object is simply a volatile store which is quite cheap. The host will then read that value using the debug probe at regular intervals and update the graph on any changes.
