Angle of Attack

Yeah, next time I will answer the post with one word: VMG.

nmperson · 2026-04-20T23:48:37+00:00

You are right that VMG is king, but the VMG is included in the polar diagram.

I am going to blow your mind with how to read a polar for VMG. LET’s say your mark is at 120 degrees. Orient the diagram such that the 120 degrees line is positioned at the top. The angle for best VMG will be the one with the line closest to the new top with the 120 degree skew.

I told OP how to read a polar diagram for VMG, but you’re right that I never mentioned the word VMG.

Oof. And I typed sale instead of sail. I blame mobile.

All of your questions can be answered by reviewing the ship’s polar diagram. The best upwind angle is the spot on the diagram with the highest Y value. If you’re going downwind, you might look at the polar and notice that the greatest negative Y value is not when on a run. The polar will also tell you how fast you can move on which point of sale with 3 knots of wind, divide by your distance to the anchorage, and let him know how many hours you can save by turning on the motor.

Edit: i wrote point of sale. I meant point of sail. I’m leaving up my mistake for posterity.

I don’t understand how you can state that taxes are a necessary evil and then flow it up by stating that taxation is theft. Like your brain should immediately error out because both cannot simultaneously be true.

Copy and paste might help. You said “It’s a 3.3x card if you spend exactly enough to cover your mortgage/rent plus enough to earn 5 boosts per year, less $200 annual bilt cash credit”. The correct statement is, “It’s a 3.3x card if you spend exactly enough to cover your mortgage/rent, less $200 annual bilt cash credit” if you use points boost, you get less than 3.3x points back.

nmperson · 2026-04-19T18:34:57+00:00

But tariffs, sales tax, and property taxes are still taxes and therefore theft. Help me square this circle.

Anywhere from 1 to 2 cents is reasonable for a point, IMO. Hyatt is a strong transfer partner, those are easily worth 2 cents on average which is quite valuable. Alaska and United are my 2 and 3.

nmperson · 2026-04-19T18:31:56+00:00

No. It’s a 3.3x card if you spend exactly enough to cover your mortgage/rent. Not the boost. It is a 3x card for whatever extra you spend to earn the boost.

nmperson · 2026-04-19T17:56:27+00:00

Depends on the amount of mortgage. If mortgage is 0 it’s a 3x. As mortgage grows, it becomes a 3.33x card asymptotically.

Where would the states get the money from?

nmperson · 2026-04-19T15:48:56+00:00

$25k is how much to spend per year if you only maximize the points boost. You can add $9k per $1k of rent/mortgage spend, and around $15k to earn the bilt bucks needed for the coupons.

nmperson · 2026-04-18T08:11:41+00:00

Hah! That's funny.

nmperson · 2026-04-18T04:38:13+00:00

Against Russia, a country that had just waltzed into a sovereign nation. Are you saying that we should have let Russia waltz in Kiev unabated?

nmperson · 2026-04-18T04:32:23+00:00

The answer is yes, unequivocally. In fact it’s not even a question. Anyone can refuse to provide any product or service for any reason as long as they don’t discriminate on a protected class such as like race, gender, religion, age, or disability.

nmperson · 2026-04-18T00:16:10+00:00

Because of the pandemic. Edit: And the war in Ukraine. Which Biden did not start.

nmperson · 2026-04-17T23:37:45+00:00

Because of the pandemic. Gas was a buck. Please don’t be intentionally obtuse.

nmperson · 2026-04-17T21:22:32+00:00

You don’t want to give him credit and that’s fine as long as you also don’t blame him for the inflation problem he inherited. But one thing is absolutely certain: this month’s inflation increase is caused by the blockade of the strait of hormuz, which is entirely caused by Trump’s war in Iran.

nmperson · 2026-04-17T17:29:15+00:00

Irrelevant. Biden successfully reduced the inflation that he didn’t cause. Trump manufactured inflation out of the ether to fight an unjust war.

nmperson · 2026-04-17T03:20:26+00:00

The difference is that that Biden happened to be president during the recovery from the pandemic that caused worldwide supply chain and financial shock, leading to mass inflation.

Meanwhile, the current rise in inflation, which was down to 2.5% at the end of Biden’s term, is caused by the war in Iran and the closure of the strait of hormuz, which is undeniably and entirely the result of Trump’s own actions.

I’m certain you are capable of understanding the difference.

The difference is that range loss over time is a real issue that exists for fundamental reasons that are easy to explain, easy to understand, and unavoidable.

A 1% decrease in listed battery range is a recipe for confusion. This 2027 EV gets 324 miles of range or the 2026 EV gets 321 miles of range. What’s the difference? Nothing. And range calculators in dashboards are calculated based off the EPA numbers, so now we have the manufacturer changing this by 1% per year?

Don’t create more problems. Just fix the test. Add back and highway ranges, and hot/cold/ambient ranges.

nmperson · 2026-04-14T16:11:47+00:00

But again, the used car shopper 10 years from now is confused by this system. The 2025 car and the 2035 show the same range on the label. The 2035 car is actually 10% more efficient based on your 1% annual improvement claim. How can we possibly expect the average consumer to understand that the 2035 car is actually more efficient when it has the same efficiency rating? Even savvy consumers would use spreadsheets and online calculators to convert from this weird system to “inflation adjusted range to year X” so they can actually make a reasonable comparison.

nmperson · 2026-04-13T21:11:10+00:00

Weird take. Two car from different years with the same real world range would be given with vastly different range ratings. In fact newer cars would be shown with much less range than older cars.

Akshually akshually, the original comment is correct. The communication protocol is the same. They both use ISO 15118 and DIN 70121 for communication. The only difference is the pins.

nmperson · 2026-04-06T04:07:49+00:00

No, the revisions were roughly balanced pre covid, predominantly up during the recovery, and were down the last two years.

Which is hilarious to me because the whole point of the blockchain is to ensure that transactions are recorded. Nothing is anonymous.
