I have what I think is a high-quality inflation pressure gauge. Its pressure readings don't agree exactly with the pressures reported by the TPM's. Others have reported similar observations.
The TPM's purpose is to alert the driver of a sudden pressure change rather than to provide extremely accurate pressure measurements. I think the TPM's work well for their intended purpose.
Same here - my racing quality pressure gauges never agree exactly with BMW's on-board TPMS readings. Not in the i3, nor in the M3.
On-board TPMS is not far off, usually within 1-2 psi of actual, but the readings are inconsistent from wheel to wheel. If I set them exactly right as measured by Longacre liquid filled gauge, but the TPMS was reading some wheels higher than actual, others lower. Kinda all over the place.
TPMS readings are a good tool to avoid driving on flat tires, or as a reminder to add more air when ambient temps drop in the winter. And that's about it.
