We're talking about the entire sequence of events, not just throwing a dummy made of sand over someone else's balcony and seeing how far some other bed rolled on carpet and floor that is different from the Spreckels mansion.
We're also not just referring to one action done in which a separate video shows a female cop who having practiced for hours is taped for live demo tying her hands behind her back with thin, easy-to-wind-up rope that is wholly different from the one used on Rebecca. Where's the tug boat hitch noose around this woman's neck? Or the t-shirt wound about her neck 3x and stuffed into her neck while she's tying her hands? Where's the rope tied around her ankle? Where's the hopping about a room in the dark with the lights off to get to the balcony? Etc.
Anyway you slice it, no one re-enacted the entire 2-hour scenario wherein a 5'3" woman of a measly 100 pounds receive the notorious, suicide-trigger voicemail, deletes it, then quickly draws up an expansive scheme in her head (note: nothing was drawn out on paper or computer or notepad or cellphone) wherein she proceeds to take a shower, run around barefooted apparently outdoors in the courtyard all naked, getting mud dirt on bottom of feet, obtained a rope, several knives, several paintbrushes, several pairs of gloves, etc. somewhere, then miraculously made a tugboat hitch noose she had never made before with no internet/book searches, tied rope around leg of bed when she could have easily tied it around the balcony and just jumped there if she were really a suicide instead of latching it inside a room re-creating a scenario similar to Max's fall off balcony, wound a t-shirt about her neck 3x taut, stuffed in her mouth, then painted cryptic message "SHE SAVED HIM CAN YOU SAVE HER" on a door in a handwriting that is not hers and much higher than at her usual level for painting, then watches Asian anime lesbian *advertiser censored* on computer, then drop paint on her breasts, then tie her hands behind her back, her ankles, then hop without making prints or leaving DNA on balcony, and at some point also managed to hit herself squarely on her own head four separate times, and also used duct tape on her legs which mysteriously disappears from crime scene...
Note: Sequence of actions I wrote above is likely out of order as I have no clue how any ONE person could have done all this on her own within a 2-hour time frame without literally and physically writing out the plan and drawing pictures to delineate what she had to do in order to accomplish the magical feat of flying off a balcony without leaving prints or DNA.
Unless you demonstrate that entire scenario without someone having memorized steps and practice/rehearsed it over and over again to get a "good take", then I call it pure BS that Rebecca did this to herself while defying nature and laws of physics.
