Rounded Up To One

A sender follows RFC 6298 exactly, with $\alpha = 1/8$ , $\beta = 1/4$ , $K = 4$ and a clock granularity $G$ of 1 ms. Two RTT samples have already been folded in:

Sample	$R'$	RTTVAR after	SRTT after
1	90 ms	45 ms	90 ms
2	70 ms	38.75 ms	87.5 ms

The third sample measures $R' = 150$ ms. After processing it, what are SRTT, RTTVAR, and the RTO the sender actually arms?

SRTT 95.31 ms, RTTVAR 44.69 ms, RTO armed at 140.00 ms

SRTT 95.31 ms, RTTVAR 44.69 ms, RTO armed at 1000 ms

SRTT 95.31 ms, RTTVAR 44.69 ms, RTO armed at 274.06 ms

SRTT 103.13 ms, RTTVAR 41.72 ms, RTO armed at 270.00 ms
