1) Note that the US is far below OECD average even in claimed testing - despite having a more serious infection problem than most.

Sure, per this data US currently has one of the highest number of cases per million population, at c.3.4k. San Marino tops the list at 17k, Vatican City at 13.7k, Spain and Iceland come in at c.5.2k, Belgium and Ireland c.4.2k. US is on a par with Switzerland and Italy at the moment. UK is at 2.6k, along with France, and Germany is at c.2k.
So US is near the top, but not exactly streets ahead of some other large 1st world countries.
2) Also: There's probably something wrong with those numbers, at least the US ones and the comparisons.
Which comparisons? The ones I gave in my post, or all the ones the data provides for?
For starters, there is little reliable data compilation in the US - tests claimed and tests actually administered and evaluated cannot be assumed equivalent.
Such issues with the data are noted in the link below the chart in the link I provided, that website also detailing where it gets its data. You are free to reject that data wholesale if it doesn't provide you with the ammunition for your agenda, of course, or you can accept the data as being broadly comparable but with some noted issues.
Continuing, we notice that a couple of countries known to have done more thorough and effective testing than the US show up as having tested a smaller fraction of their population (S Korea) - that is possible on competence considerations, but would not reflect well on the US regardless.
Sure, the number of tests per population is clearly not in itself an indication of competence or otherwise. This is not disputed. I posted merely to show that the US is by no means the worst in terms of testing per population. Measuring the number of tests per population is really only good for comparing how many people have been tested. Some countries have tested far fewer and have far lower cases. Some have tested more and have higher cases per million (e.g. Belgium, Iceland etc).
3) The US testing has been largely confined to symptomatic people - a much smaller and more specialized target population than a competent government, confronted with a viral plague, would select. That is "inadequate" testing, as posted, and due to incompetence and corruption, as noted.
Sure, and this is likely true of some other countries that need to prioritise testing capacity. The UK have done this (as well as prioritising frontline health workers where possible) and is now getting to grips with the number of tests it set itself to perform. Now, if you have the equivalent information (of who is being tested) for the other countries so as to validate your concern regards comparability...?
4) The "total tested" figure has been removed from the US CDC website (the US has no reliable and official source of such data), but it is hardly likely to be in the neighborhood of 5 million (as would have been required by the claim of 15.6/1000 citizens tested). This graph from the CDC indicates less than 1 million tests evaluated:

Sure, and that chart clearly indicates that it is measuring the tests at
public labs. Given that
private labs in the US are conducting c.90% of the tests, is there a reason you are ignoring them? The data behind the chart in the post I linked to certainly includes such testing at private labs, as far as possible.
Note, I am not saying the US, or UK, or any other country's government is competent or otherwise. I'm simply laying out some data that is publicly available on the matters of testing, infections etc. Most of it can probably be found on Wikipedia as well, if that is more to one's taste. If, however, someone tries to make an argument based on such data, I am interested to see how far the numbers do actually support it.
