    I was wondering if you guys know how to estimate the Time on Ice of a player ? I know that there's a study out there but I'm having difficulties to understand the way they proceed. Is there a formula already built ?

    Thank you

    I don't know who made it...but @seventieslord gave me my copy years ago. I think it was based on like shots and plus/minus or some such...assuming you're talking about pre-1998.

    My assumption is that the thread starter is looking for the estimate used in years for which TOI is not published.

    Iain Fyffe created the method most commonly used today; there's a useful thread about it here:
    https://hfboards.mandatory.com/threads/principles-of-estimating-ice-time.1731329/

    Basically, the method was created by fitting a model to the known data, and then assuming that the same relationships would hold in prior periods (that second part is a bit controversial - since it's different to extrapolate than to interpolate - and gets talked about a bit in the thread).

    situational goals for and against, compared to the team totals.

    Thanks for your answers guys. I was looking for a formula that would help calculating/estimating TOI in the QMJHL. As I look on their Stats page, I can't find the TOI of players.
