The overall length of bending wood must be about 2.3 times the draw length. Narrow bows (known as "longbows") can bend in the handle. Wider bows (known as "flatbows") must be narrow in the handle if they are to be practical, but the handle must be made thicker so as not to bend, and the complete bow will therefore tend to be longer.

Draw lengths of the arrows varied between 24 and 32 inches (61 and 81 cm) with the majority having a draw length of 30 inches (76 cm). [22] The head would add 2.0 to 5.9 in (5 to 15 cm) depending on type, though some 0.79 to 1.77 in (2 to 4.5 cm) must be allowed for the insertion of the shaft into the socket. [81]

Lastly the four rhomboids that form elongated crosses also give the magic sum: 23+1+9+24+8, 15+1+17+20+12, 14+1+18+13+19, 7+1+25+22+10. Such squares with 1 at the center cell are also called God's magic squares in Islamic amulet design, where the center cell is either left blank or filled with God's name.
The drawdown duration is the length of any peak to peak period, or the time between new equity highs. The max drawdown duration is the worst (the maximum/longest) amount of time an investment has seen between peaks (equity highs). Many assume Max DD Duration is the length of time between new highs during which the Max DD (magnitude) occurred.
