In reply to Mark Warnett: Hey there...
Iv'e used the beastmakers alot especially recently and as mentioned before once a week might not be enough. Once a week may keep you at a stable level where you don't decrease in strength, but you certainly wont improve at a great and noticeable rate. Instead I'd recommend using the fingerboard a minimum of two times a week.
However you may also be becoming conditioned to the usual sets of repeaters you do too, so mixing up what you do will also be important. Give changing the degree your arms ago as this will increase the intensity. (Good tips for this can be found on the beastmaker website.) You can also change around the fingers you use while dead hanging e.g. If your hanging off your middlefinger and ring finger try you index and middle finger.
Furthermore you could do deadhangs one session and do a more personalised session the next time you use the board. Here is a basic 20 minute workout for individuals are around beginner/intermediate level. However this is for the Metolius fingerboard so just change it up so your using the holds on the beastmaker 1000 or 2000 to make it harder.
Hope this is some sort of help and I haven't chatted to much shit!
