When hovering over the electric mining driller sitting on an uranium ore patch the dialog shows "Mining speed: 0.5/s". Experiments and the Wiki for Electrik Mining Drill show 0.25/s instead.
Found this playing 1.0.0 but verified in 1.1.12.
[1.1.12] Electric driller shows wrong mining speed for uranium ore
Re: [1.1.12] Electric driller shows wrong mining speed for uranium ore
The mining speed is just specifically talking about the mining drill, you need to multiply it by the resource 'Mining time', which is 200% for uranium
Re: [1.1.12] Electric driller shows wrong mining speed for uranium ore
IMHO not exactly: The "mining speed" for the mining drill as shown in the wiki page is indeed a multiplier and as such has no suffix (sic?) like "1/s". The "mining speed" as shown in-game does have the suffix "1/s" and thus implies that it is the effective value.
The next point is: "mining time" is not visible in-game for standard ores - only for uranium. This makes this surprising behaviour.
I see two solutions:
a) Simply strip the suffix "1/s" from "mining speed" in the dialogue in order to align it with other occurrences of factors like "crafting speed" for assemblers.
b) XOR really print the effective value for mining speed.
Note for the last option: IMHO one of the biggest learning hurdles of Factorio is: Not all factors are shown consistently upfront, they are nowhere explained in-game AND the effective values are not shown. This often leads to this situation: "Hmmm. Why is this design not working any more. For X it worked. What d**n factor is now "introduced" for Y?" Simply also showing the effective values would help quite much.

That doesn't really work since a miner could be touching multiple kinds of ores with different mining speeds. Then you'd need to arbitrarily choose one to show, constantly change the number to match the next ore being mined, or find some way to average all the possible speeds. None of those would end up with a useful number showing.
Re: [1.1.12] Electric driller shows wrong mining speed for uranium ore
Leaves option a) -- just strip the suffix "/s" to align "mining speed" with "crafting speed" and similar stuff.
But just now it is considered "not a bug"
