As I’ve understood, Delta chat is based on the IMAP protocol and uses the infrastructure of your email provider. Thus, it uses no own server infrastructure, but has the also the downsides of the protocol and some issues with many email providers.

AfaIk, the tachometer is allowed to be overestimating your velocity by 10 %. On my car, it’s pretty accurate when using 15" the factory default summer tires, but it’s off by 10 % when using the factory default 14" winter tires.
Yes, essentially, an email is the digital equivalent of a postcard.
In my installation, I use descriptive names like, e.g. ‘wall light couch’, ‘ceiling light living room’, etc. or ‘night light’, ‘bright’, ‘mood’ for scenes.
Looking at the ideal gas law, p·v = R·T (v is the specific volume, the inverse of the mass density), I’d say beside the pressure p, i.e. the weight of the atmosphere above a point, it’s at least the temperature T that is quite different between Earth and Venus. An other factor is the compressibility of the fluid; our air is quite compressible, the atmospheric pressure is quite low and the ideal gas law thus gives a good approximation.
As an atmosphere consisting of multi-atomic fluids, on Venus mainly CO_2, in an over supercritical state is far beyond what can be considered to be an ideal gas (low pressure, single-atomic gas), there are several other factors to be taken into account. The van der Waals law or the Clausius law are usually models to choose when dealing with real gases. However, as mentioned, the atmosphere is in an over supercritical state, i.e. beyond the critical temperature and pressure, the fluids are not in gaseous state, thus an even more complex material model is needed, to describe its behaviour.
But to give an idea of the effect: When you measure the pressure and the density of the water of an ocean in different depth, you’ll notice the pressure increases linearly with depth, while the mass density of the water remains almost constant. Its low compressibility is why water often is treated as an ‘incompressible’ fluid. Similarly, this may work in an over supercritical fluid, as it has some properties that are similar to gases and some, e.g. lower compressibility, that are more similar to liquids.
I don’t want to be nitpicking, but, while at ground level, the atmospheric pressure is 92 bar (Earth: ~ 1 bar), the Venus atmosphere at ground level is ‘only’ 50 times denser than on Earth, 65 kg/m^3 vs. 1.2 kg/m^3.
Yet, 2-4 km/h wind velocity in the over supercritical atmosphere on planet Venus are not directly comparable with some wind here on earth.
I know, but still the circumference differs. It’s 195/60R15 vs. 185/65R14
Obviously, the 10 % difference are just a feeling.
