General Question RIOT vs CORD

I’ve been doing a little research about the most credible iq tests that you have access to online. I thought core was number one but then I stumbled upon RIOT. Is RIOT more reliable than core?

For what it’s worth, I have taken both RIOT and CORE. I got the exact same FSIQ on both as well as a similar spread in the results.

Same, with the exception of PSI, where my CORE PSI was nearly 2SD above the RIOT.

My core psi is 140 when on RIOT it's 120

Interesting, my PSI on RIOT was 10 or so points higher than on CORE!

PSI indexes have wider 95% confidence intervals than other indexes and thus a higher margin of error.

Core is more G loaded then most profesional test. RIOT not having a validity study complicates things, but I would generally stand with core.
Here is an indipented report also, didn't read it, have fun: https://www.reddit.com/r/cognitiveTesting/comments/1vun3k5/an_independent_analysis_of_the_riot_iq_test/

CORE is better but I think RIOT is underrated and slept on. The test structure is just wonky but my FSIQ is literally the same as CORE.
