Progress Charts (100 sheet packs) The proprietary Great Leaps Progress Chart developed from the Standard Behavior Chart by Kenneth Campbell is an equal ratio one-minute chart. The chart shows relevant movement whereas the usual equal interval chart - or graph paper - cannot. The Great Leaps Progress Chart shows relevant movement via percentage gains – making it a multiply-divide (acceleration-deceleration) chart. Detailed instructions are included in the 3 pages before the blank charts in the Appendix of each book. A blank progress chart is available on the Great Leaps website in PDF format download chart PDF(68k). The Great Leaps Progress Chart is an essential element of the program.
