That's a good shot at it, but the problem there is that I can only allow one "doubling" that has no play effect. That is, let's assume you're working on the kick about three and a half hours a week, when you combine all your sessions. Now you want to double the speed of the kicks, which means you'll do them faster but still within the three and a half hours, and you want to double the number, which means you'll do more but still within the three and a half hours; and at some level I'm thinking that the only way you can do twice as many kicks in the same time is by doing them twice as fast, so you've really only doubled one thing. Still, even if you were to say that you were going to do twice as many in that time and wear ankle weights, I wouldn't have a tangible effect on the character.
The easiest and most obvious thing to double is the practice time. Given that there is skill overlap (you practice the style and the kicks as part of the same session, and thus you practice longer than you would for any one skill but not as long as you would for all the skills individually) you wouldn't have to add the base time (sixty hours in one hundred days) for each kick, but a reasonable increase based on the amount of overlap--in this case, since they're all kicks, I could see an increase of about half the time for each, a total of ninety hours over one hundred days for the three kicks.
Of course, we've not really defined how much time you have put into practice for the martial arts. Let me do a bit of open math here to get something of an understanding of how much you're practicing. Here are the skills, with their current skill ability levels, and the number of hours over one hundred days you would be expected to spend working on them to benefit; then we'll find a formula to total them and break them down to your weekly practice:
- 1@7 Aggressive Running Frontal Power Boost B3@10 uses one attack RS=+DC to next forward kick-based attack (Power Front Kick), on failure fall for damaging damage: 60
- 1@7 Aggressive Running Side Slide B3@10 uses one attack +RS=SM to next side-arc kick-based attack (Side Kick, Flip Kick): 60
- 2@3 Eli's Style B7@1 Fast Aggressive Weapon-utilizing style, kick- and punch-based, RF2, +10 Att SM +10 Att Dam Mod: 120
- 2@3 Back Kick B7@1 basic attack on opponent directly behind: 120
- 1@5 Bo Stick B7@1 RF1 damaging two-handed: 60
- 1@7 Elbow Strike B7@3 base dangerous attack at close range RF1 -10SM: 60
- 1@10 Back Kick B7@3 base dangerous RF1 -10SM, +10 opponent attack SM: 60 to now, 120 to continue
- 1@10 Power Front Kick B7@3 base damaging -10SM: 60 to now, 120 to continue
- 1@7 Flying Side Kick B7@3 base dangerous RF1 -10SM, on failure lose balance and forfeit next attack: 60 to now, 120 to continue
- 1@10 Roundhouse Kick B7@3 base damaging RF1 -10SM: 60 to now, 120 to continue
That's 60+60+120+120+60+60+60+60+60=720 hours over 100 days if you were tackling them individually. However, the two Aggressive Running skills are quite similar, so that takes off 30 for the second; you've also got two distinct back kicks listed (one a basic tactical attack and the other an intensified damage version), so that's -30 for one of those; and I've already said that the other two kick maneuvers are similar enough, so that's -30 for each of those, and the flying side kick is also in the same category so -30 for that. That's -250 from that 720 which leaves 470 hours over one hundred days, 4.7 hours per day practicing on martial arts (but what else do you have to do?). One tenth of an hour is six minutes, time 7 is 42, so you're spending between four and a half and five hours a day on this. (You're also spending 120 hours over 200 days for each of your strength training and aerobics/running to get the strength and stamina benefits; that comes to six hours (total) every five days, or about an hour and a quarter per day. Your medical training runs about the same time, and your Japanese runs concurrent with that, mostly, but is another fifteen minutes per day of focused time. These might not be on a consistent schedule--you might do a couple hours of medical one day and none at all the next--and that applies to everything, as long as you're doing them all several sessions per week.)
To double the time spent on these three kicks, you would have to add almost an hour a day to this. I'll also note that your load will increase again when other skills reach that maximum amateur line (1@10), including the work you're doing in Japanese and herbalism.
