The first time is reasonable, if fast, however 783W for 3 mins is too
high to be real I'd say.

I think it is 705 watts. The high estimate may be a result of my Javascript
formula which gives the power output as:

9.81*w*10*(1191/t)/100

where 9.81 is gravity,
w is weight of bike and rider in kilograms,
t is time taken in seconds,
10/100 is the gradient and
1191 is the distance in metres.

If you look at http://www.compbio.dundee.ac.uk/~dmamartin/arthurs.png there
is a route profile traced from the OS map. The profile is 1.21 km long and
rises from 38 to 121m.

So your power calculations are a bit off (too high by at least a fifth).
