Thanks for the feedback and the kind words, The specific reason as to why I didn't do percentages is because at the time of writing the exact reinforcement number hadn't been set in stone and because people are bad at Percentages; so fixed numbers helps alleviate that problem. I eventually concluded that a fixed recommendation of an extra 1000-1500 points would be better due to the possibility of the Attacker rolling 6s on each round. Unlikely to happen, but I have had that happen.
