Academics with very high RG scores seem to rely on numerous Questions and/or Answers, but they also seem to have relatively low TRI and h-index.

The h-index does not affect TRI, which would be even lower if it did.

To Chia-Ling Chang:

Thank you for your helpful response.

As a widely-accepted measure of research quality, the h-index would be an excellent accompaniment to Citations in a modified TRI.

The RG score is a measure of academic social activity, and is not related to research quality, Citations, or the h-index.

It might be worth noting the following serious issue relating to the RG score:

It is probably because RG is a mixture of scientific platdorm and social network, so it wants to reward both activities.

To Mirna Leko-Šimić :

Many thanks for your helpful and informative response.

I enjoy the endless discussions in Q&A, where everyone seems to have an opinion.

This should be encouraged as most Questions are open ended and do not have uniquely correct Answers.

In connection with the RG score, as of 26 May 2019 I have compiled a list of 126 academics with RG score > 100.

I do not pretend to have a comprehensive list, but I am able to provide some data to support and encourage sensible empirical discussion about the RG score, whether you care about the RG score or not.

In my list, the highest RG score = 965.45, with h-index = 27.

Of the 126 academics, 32 have h-indexes in the range [0, 10).

Two academics have h-index = 0, and four have h-index = 1.

The remaining 94 academics have an h-index in the range [10, 91], with more than one-half of 94 having h-index > 25.

The majority of the 126 academics have h-index > 20.

This is not achieved through endless Q&A, contrary to what has been repeated in various threads relating to the RG score, but through serious academic research over an extended period.

I would like to thank all the academics who have provided interesting and stimulating Answers to the Question.

Not even TRI, which is a measure of academic research quality, depends on the h-index.
