Meaningless statistics behind the SMRT’s claims of improvement for its MRT lines

Reliability of MRT lines improves
I refer to the article “Reliability of North-South and Circle MRT Lines improves; East-West Line maintains same standard” (Straits Times, 24 Apr 2017).
It states that “In the year ending Q1, the NSL clocked an average of 180,000km before a delay lasting more than 5 mins, bettering the 156,000km registered in the year ending Q4, 2016.”
Trains travelled longer distances before delays?
According to an article “MRT network performance up 30 per cent in 2016 from 2015” (Straits Times, 12 Jan 2017) that was published earlier this year – “last year, trains clocked 174,000 train-km travelled between delays of more than five minutes, a 30 per cent increase from 133,000 train-km in 2015.”
Last year’s was 174,000 or 156,000 km?
So, how is it that “last year, trains clocked 174,000 train-km travelled between delays of more than five minutes” has now been apparently become “before a delay lasting more than 5 mins, bettering the 156,000 km registered in the year ending Q4, 2016”?
So, is it 174,000 or 156,000 km travelled between delays of more than five minutes, in the last year?
As to “The EWL, however, maintained the same level of Mean Kilometre Between Failure (MKBF) – a key measurement of reliability -of 145,000 km for both periods. The CCL improved its MKBF to 282,000km from 228,000km previously” – Who cares how many km travelled between delays?

A train delay is still a train delay which cause thousands of people to be late for work and appointment .
