Jolly Roger, The skills were built using the optional rules for variable stat bonuses as laid out in Appendix A-9.2 page 293 of the RMSS Standard Rules. "When using this optional rule, each skill category bonus uses the first two stat bonuses given for the skill category (given in the Skill Summary Table T-2.5 and Appendix A-1). Then each skill gets a special bonus that is equal to the stat bonus for the stat given in brackets (i.e., {xxx}) after the skill's description in Appendix A-1." Largely because I built the sheet and that is how my groups have played the game for the last 20 years. If you wish to change the skill stats around without creating your own
custom sheet, you can, for example, put " -@{sdbonus}+@{agbonus}" in the
special bonus for Acting which will return that skill to using agility
instead of self discipline for the third stat bonus. The +10 to body development is from the description of Body Development on page 160 in the RMSS Standard Rules: "All characters receive a special +10 bonus to this skill." And from the same page, "Normally, this skill bonus consists of the following: Body Development skill bonus = 10 + (2 * Co stat bonus) + SD stat bonus + profession bonus + skill rank bonus + any special bonuses." On the sheet that looks like: <div class="sheet-table-row">
<span class="sheet-table-data-skills-cat-name">Body Development</span>
<span class="sheet-table-data-skills-cat"><input type="text" name="attr_bodydev" title="bodydev" value="10+@{bodydevrankbonus}+@{bodydevstat}+@{bodydevcatbonus}+@{bodydevspecialmod}+@{bodydevitemmod}" disabled="true"/></span>
