Great news - glad you use the website and glad your formula works. I spent some time on this, It is possible to provide accurate distance - thats fairly easy. But accurate walking time is impossible for lots of obvious reasons. But what I have tried hard to do (and this is a hint for the Tassy project) is to use a consistent method for calculating walking time. My thinking is that the time should be just on the longer side of a 'typical user'. Once you have done a couple of walks within a parks system you should be quickly know how the timing fits your walking style.
With grading. Again I use the AS 2156.1 - 2001 There is a lot of pressure to dump this and use a new system Developed out of Victoria. One benefit (I would suggest the only benefit) is that it focuses more on providing information about the track - rather than just the grading. But the AS 2156.1 also allows for this - it is just rarely used. The new Victorian system ignores two safety elements from the AS that are critical for beginners and I therefore think the use of the Vic system is dangerous and I would strongly advice against using it. The AS 2156.1 is not perfect either, but can be improved upon.
<Start My rant>
NSW NPWS is adopting the Victorian system - I think it is a terrible move - I just do not understand how a Govt department can ignore the safety recommendation of an Australian Standard.
<end my rant> thanks I feel much better now

A few other bits (since my e-mail the other day)
Can I also suggest that the Tassy system considers
1) the needs of people with English as a second Language. The use of pictograms and photos on information (if done well) can convey messages better than text.
2) letting people know where (eg URL) to find weather forecasts and Park closure information
