In the current tenure-track job market for stats PhD's, are we seeing more post-docs or more fresh PhD grads land assistant professor roles?

I'm a 2nd-year PhD student in statistics in the U.S. at what I'd say is probably a top-15 program, though perhaps not top 10 and definitely not top 5. I'm on track to graduate after my 4th year and my goal is to eventually land a tenure track role at a research-oriented university (either R1 or R2). I still have a couple more years before I have to worry about this, but I'm trying to determine whether to do a post-doc after my PhD, or attempt to land a tenure track position right away. I know it will ultimately depend on how my upcoming papers/publications ago, since a post-doc buys me more time to submit more papers. But I'm just curious to get a general sense of what the tenure track academic job market is like for stats PhD's, and how necessary/helpful a post-doc is. Or, alternatively, roughly what percentage of new assistant professors at research universities are arriving from post-docs as opposed to fresh out of PhD programs?

In biostatistics, I'd say that 75% or more of new hires at top 20 places have a postdoc under their belt. But it's certainly possible to get hired straight out of a PhD.
