How closely does Cleary's translation adhere to the original Blue Cliff Record?

I'm interested to know the academic consensus on Cleary's translation of The Blue Cliff Record. I've heard that his translations could be spotty at times, given that, how accurately has he depicted this text? To clarify: I want to know how closely Cleary's translation adheres to the original Blue Cliff Record, not how the Buddhist community regards it in terms of Buddhist practice.
