But, an apology is also in order: the 70% number on our website is more misleading than I thought it is. Our test runner skips entirely Annex B[1] _and_ Intl tests; one could perhaps view the 70% number then as "percentage of ECMA262 specification done". The 58% value reported by test262.fyi is probably the correct value (unless we have a bug with debug prints that causes spurious failures there).

[1]: I remembered that we skip Annex B tests; those are fairly few in number and we pass 40% of them anyway, so their effect isn't large. Didn't remember the other category we skip, and absolutely didn't remember that it's a major one like Intl.
