Uh, what? You’re overly attached to the MWD trick. Just because it works great for cloak+MWD when hauling goods, doesn’t mean it’s great for all instances where ships take >10 seconds align time.
That’s because you’re comparing Higgs with trying to warp off with MWD trick, which is like comparing Olympic sprinters with Polio survivers on “who runs faster”. Have you not yet mined with a Higgs rig on before? Here is how mining with Higgs works:
Mine a rock. MWD is off – if you even fit one. Pre-aligned to station / tetherable structure / deep safe. Travelling at 75% of 36 m/s (using your own numbers) or 27 m/s. Hitting “warp” takes you 0 seconds to enter when mining in this configuration, which is a lot faster than 10 with the MWD trick and still faster than the 9.4 abomination you created.
In 1 minute you travel 1.6km, so you have 9 minutes of mining at this fast speed with 15km range of strip miners. If you are in a fleet receiving boosts then you can get more range and therefore stick around in the belt longer. Plus you can fit your ship to be stupid slow, more slow than 27 m/s, you can drift far less distance in the same amount of time, which means you can stick around in a spot way easier.
The only vulnerability is the X seconds it takes your fit to get to 75% speed to pre-align right after you land. After you land and pre-align, your entire mining session is 0-seconds-to-warp safe. If you’re bookmarking warpin spots in a belt in advance and have deep safes in the proper orientation with a cheapo frigate or something, that’ll indeed be your only vulnerable time period – b/c even when I give this advice, some people still try to create bookmarks in this slow fat brick!.
Compare that temporary X seconds vulnerability to the guaranteed 10s vulnerable time you have with the MWD trick. Sure, X will be larger than 10, but complaining about that and preferring the 10 is like saying two pennies are more valuable than one quarter.
Hope this elaboration helps clarify.
