WELL, the Hundred Power is pretty much What It Says On The Tin, which is 100x the physical capabilities of its user, soooo one tenth would be approximately 10x the strength of a 5'11'' 37-year old man who's in really good physical shape (i.e. of someone who's been working out and fighting high-profile crime continuously for 11+ years)

the hundred power kind of encompasses a lot of things (he uses it in canon as an improvised healing factor and to strengthen his hearing) though so for the purposes of this please let me know if i need to limit it to strength/speed/one or the other.

please let me know if i need to google a point of reference for "normal" human strength for this.
