Two weeks of commuting by train

My new house is 34 miles from my workplace. Google suggests it should take at 1 hour 15 minutes to commute by train, which comprises two ten minute walks at each end, a forty minute and a ten minute train journey, and a five minute wait for the second train in the middle. After doing this journey fourteen times over two weeks, how accurate has it been?

	To work	To home	Delay reason
Week 1
Monday	1h30	1h50	first train was delayed by 13 minutes, causing me to miss my next train, and the following train was delayed
Tuesday	1h20	1h15
Wednesday	1h30	1h15
Thursday	1h20	1h15
Week 2
Tuesday	1h15	1h15
Wednesday	2h15	1h15	first train was delayed by 35 minutes, second train was cancelled and following train was delayed, adding another 25 minutes
Friday	1h15	1h25	Trackside fire delayed train

Ideal total time, home to work to home: 75 minutes x 2 x 7 = 1050 minutes
Actual time: 1195 minutes
Average delay: 10 minutes per journey
Longest delay: 60 minutes
