ch07: 2-of-5 instead of 2-of-3 for Mohammed's example 
The example is a 2-of-5 multisig, according to the Pay-to-Script-Hash example description earlier, and the P2SH example a few lines below.

Correct transaction costs in segwit example 
The transaction fees in the example were off.
2-of-3 P2SH inputs are between 293 and 297 bytes (293 bytes if both
signatures have low-R, 296 bytes if one signature has high-R, 297 bytes
if both signatures have high-R) and P2SH outputs are 32 bytes.

2-of-3 P2WSH (native segwit) inputs are between 104 and 104.5 vbytes
(416–418 WU, depending on low-R/high-R as above) and P2WSH outputs are
43 bytes.

The transaction header has 10 bytes for non-segwit transactions and 42
WU for segwit transactions.

Source:
https://github.com/BitGo/unspents/blob/master/src/dimensions.ts#L69

I have updated the numbers in the example and amended the conclusion
which did not match the new numbers. Calculation details follow.

-----

Let's assume that the wallet is using signature grinding and will always
produce signatures with low-R:

•Without Segregated Witness:
Transaction A using 2-of-3 P2SH inputs and P2SH outputs:
3*293 + 10 + 2*32 = 953
953 * 30 = 28,590

Transaction B using 2-of-3 P2SH inputs and P2SH outputs:
2*293 + 10 + 3*32 = 692
692 * 30 = 20,760

•With Segregated Witness:
Transaction A using 2-of-3 P2WSH (native segwit) inputs and outputs:
3*104 + 10.5 + 2*43 = 408.5
408.5 * 30 = 12,255

Transaction B using 2-of-3 P2WSH (native segwit) inputs and P2WSH
outputs:
2*104 + 10.5 + 3*43 = 347.5
347.5 * 30 = 10,425

Specify height/timestamp cutoff for nLockTime 
Changed "If it is above 500 million..." to "If it is greater than or equal to 500 million" to more accurately reflect the protocol spec.
